Rebecca Foley, 21, was shot and killed while driving her car near her Savannah, Ga. apartment on Jan. 21, 2013. The case remains unsolved.

It's been four months since a hard-working Georgia college student named Rebecca Foley was shot to death in her prized red Volkswagen Beetle as she drove up to her well-manicured condo development.

The case was front-page news in Savannah, and Foley's death was highlighted in an NBC News investigation of gun deaths across the country over the long Martin Luther King Jr. weekend in January.

The attention did not help police crack the case, though, and now Foley's family has jacked up a reward in hopes of shaking loose some leads.

"Somebody, somewhere knows something," said the victim's father, Eddie Foley, who added $10,000 to the reward money for information leading to an arrest and conviction. "I don't want it to become a cold case and I feel like that's what it's becoming."

On the evening of Jan. 21, his 21-year-old daughter was found slumped over her steering wheel, dead from a single bullet that left a hole in the rear window. She had just gotten her nails done and planned to meet a friend at home.

Those who knew Foley described her as a striver with a bright future, a pretty young woman who juggled several jobs to put herself through college and hoped to go into the insurance industry.

Her family thought she must have been the victim of mistaken identity, a gang shootout, or a robbery gone wrong. They assumed a witness or a suspect would soon surface, but weeks have turned to months with no arrest.

Foley's parents, who are divorced, made a public appeal with police in March. Her father traveled from his home in Gastonia, N.C., to Savannah last weekend to spend two days papering the city with fliers.

The Savannah-Chatham Metropolitan Police Department said there is no progress to report.

"There's no closure. We're not able to move on," said Foley's mother, Jennifer, who considered and then decided against hiring a private investigator.

She said she has joined a bereavement group and is seeing a therapist, her grief compounded by uncertainty.

"I feel this incredible, overwhelming sense of helplessness. It feels like nobody cares," she said.

O.C. Welch cares. The Savannah-based car dealer, who has offered rewards in several other unsolved homicides, kicked in $2,500 for the Foley investigation. Along with the standard $2,500 offered by Crimestoppers, that brings the total to $12,500.

"Never met 'em," Welch said of the Foleys. "Don't need to know 'em. Just trying to help. Ain't that what you're supposed to do?"

Eddie Foley said he's hopeful the cash will yield some clues — and some peace of mind.

"I can't bring my daughter back, but it's very important we bring justice and get this person locked up," he said.

A New Jersey man who admitted to murdering a teenager 23 years ago said he turned himself over to police because the guilt has haunted him and made his life "a living hell."

Steven Goff on Monday confessed to police that he stabbed 15-year-old Frederick Hart on May 7, 1990 in Galloway, N. J., according to the Atlantic County Prosecutor's Office.  

The boy's body was not found until December of 1991, and was so badly decomposed that it was unclear what the cause of death was.

In a phone interview from jail with Atlantic City' NBC40.net, Goff said he made the admission because the memory made life "a living hell."

"I wasn't worried about getting caught. I had no chance of getting caught from this crime, whatsoever. I was away scot–free but you know, that doesn't mean that it was away in my mind," he said.

But it may have been more than just guilt.

Alan Rickel, a friend close to Goff, told the Associated Press that the confessed killer would be haunted by a vision of the dead boy's mother. 

"He couldn't bear it anymore," Rickel told The Associated Press. "He told me he had nightmares. He'd go to sleep and see the kid's mother staring in his face."

Rickel said he knew his friend had psychological problems and thought he was in need of medication. He helped Goff return to New Jersey from northern Michigan, where the troubled man had been contemplating a run for the Canadian border. But soon after Goff returned to the Garden State, Rickel got a call from Galloway Township police saying his friend had admitted to the killing.

In a court appearance on Monday to be presented with charged against him, Goff told the judge, "I did the crime" and said he wanted to expedite the judicial process.  

But Judge Michael A. Donio cut Goff off during the unprovoked confession, warning "anything you say here today can be used against you."

As the judge read back the details of the crime, Goff wept.

Goff, who was 18 at the time of the killing, is charged with murder and unlawful possession of a weapon for an unlawful purpose. He is being held on $1 million bail.

San Diego Police Dept.

Pedro Antonio Guzman-Gonzalez is wanted in connection with a 1990 murder.

Exactly 23 years to the day after Maria Vargas was found strangled to death inside a home in Logan Heights, San Diego, homicide detectives renewed appeals for the public’s help in finding her killer.

On March 17, 1990, San Diego Police Department officers responded to reports of a death at a home in the 2900 block of National Avenue.

When officers arrived at the scene, they discovered Vargas’ lifeless body in the bedroom of her boyfriend, Pedro Antonio Guzman.

Detectives say Vargas had been strangled to death. Guzman had fled the scene before police could question or detain him.

Since that St. Patrick’s Day murder more than two decades ago, police have been after Guzman, who’s suspected of killing Vargas.

Detectives say it is likely Guzman, who is now 49 years old, fled to Mexico following the murder.

He is described as 5-foot to 5-foot-3, Hispanic and weighing approximately 140 pounds. He has black hair and brown eyes. Guzman was 26 at the time of Vargas' murder.

On Friday, the SDPD released a photo of Guzman in hopes of locating him and reopening the case.

Detectives are asking anyone with information on his whereabouts to contact the SDPD Homicide Unit at (619) 531-2293 or Crime Stoppers at (888) 580-8477. Up to a $1,000 reward is being offered for information that leads to the arrest of Guzman, and tipsters may remain anonymous.

Published at 5:09 a.m. ET: One of the best-known child kidnapping cases in the country is back in the news.

San Francisco Police Chief Greg Suhr held a news conference Wednesday to announce they now have a "person of interest" in the 1984 disappearance of 10-year-old Kevin Collins. He was last seen walking home from a basketball game and has not been since. His face was one of the earliest to be put on the back of milk cartons across the country in the search for missing children.

"This case is a case that haunts the San Francisco Police Department," Suhr said.

Suhr identified the man as Dan Therrien, who lived in a home just a couple of blocks from where Kevin was last seen in 1984, near the corner of Masonic Avenue and Page Street in the Haight-Ashbury neighborhood. Therrien died in 2008.

Complicating matters, Therrien went by at least five aliases. Police said he used the name Wayne Jackson at the time of Kevin's disappearance.

San Francisco Police

San Francisco Police Chief Greg Suhr held a news conference Wednesday to announce a "person of interest" -- Dan Therrien, shown in 1982 -- in the 1984 kidnapping of 10-year-old Kevin Collins.

Police stopped short of calling him a suspect, and instead said he was a "person of interest." Suhr also asked for the public's help in coming up with any information that might be relevant to the case.

At the conference, police said that detectives realize this is a long shot, but they're just hoping someone will remember him.

Investigators looking at the case recently realized Therrien had a lengthy criminal past in both California and Canada, including a felony for a lewd act on a child. They didn't know that at the time because he had used other names. Police said that in 1981 he had served six months in jail after pleading guilty to a felony charge of a lewd act on a child. The victim was 7 years old.

The Canadian case was also previously unknown: He was arrested in 1973 on suspicion of kidnapping and sexually assaulting two 13-year-old boys.

In the Canadian case Therrien -- whom police also identified Wednesday as Wayne Jackson -- went on the lam and was never arrested. Police didn't release where it happened in Canada or any other details.

Therrien was eyed by police at the time of Kevin's kidnapping, according to sources, and he had consented to a search at the time. But he was never formally arrested or named a suspect in Kevin's disappearance.

Kevin's story captured national attention. He was last seen was on his way home from a basketball practice at St. Agnes School in the Haight-Ashbury neighborhood. He was talking to a man with blond hair and a large black dog, waiting for a bus at the corner of Oak Street and Masonic Avenue. Normally his older brother would have been with him, but that day his brother was home sick.

Police said Therrien matched the general description of that man and had a black dog at the time.

Last month, San Francisco police searched the home where Therrien lived in 1984 and removed several bones that were located under concrete in the garage. But those bones turned out to be from a small animal.

Cold-case investigators said last week that they realized recently that cadaver dogs were never used when the home was searched in the 1980s.

On Tuesday night, the the lead cold-case investigator visited the home of Kevin's mother. Investigators spent a couple of hours with the boy's family and left without comment. They said they showed the family photos of Therrien at the time Kevin went missing to see if they family might have known him.

Kevin Collins would have been 39 years old on Jan. 24.

"What we're looking for now is anybody that saw this guy in 1984, anybody that talked to this guy back in 1984, anybody that talked to somebody that talked to this guy back in 1984," Suhr said. "We would love to find the whereabouts of that little boy."

Anyone with information on this matter can contact the SFPD Major Crimes Unit at (415) 553-1145. Information can be given anonymously at (415) 575-4444.

Three decades have passed since Robert and Goldie Huntbach were found tied up and shot to death in their Waterloo, Iowa, home, and no suspects were ever arrested in the elderly couple's murders -- until this week, when one of them voluntarily walked into police headquarters and confessed.

"There were a lot of suspects at the time that we looked into," Waterloo police captain Tim Pillack, who was working for the department when the Jan. 12, 1981 double homicide happened, told msnbc.com. "We just were never able to get enough probable cause against somebody to make an arrest."

The case eventually went cold. Then, on Tuesday, Jack Wendell Pursel showed up at the police station in this city of nearly 70,000 with something to say.

"Basically, he just wanted to talk to someone about it," Pillack said. "We had one of our investigators interview him, and he confessed to killing them."

Pursel, 66, told the investigator he had planned to rob and murder Robert Huntbach, 85, and Goldie Huntbach, 75. He gave details that only a person involved in the crime would have known, but Waterloo police didn't release what those were.

The homicide was grisly: Robert had been found in the couple's dining room, blindfolded, with a dish towel in his mouth, according to Waterloo Daily Courier archives. He had been hit with a blunt object. Goldie was in a hallway, blindfolded, with a clothespin on her nose, The Daily Courier said. An electric cattle prod had been discovered in the master bedroom, and Robert had injuries on his chest and wrists that may have come from the device.

It's unclear whether Pursel knew the Huntbachs, who were retired at the time of the killings. But he had been one of the suspects that Waterloo police interviewed early on in the case.

"From what we were able to find, he knew one of the victims' children or grandchildren -- I believe their grandchildren," Pillack told msnbc.com. "He was one of the suspects way back when that we looked into at the time."

Police have no idea what prompted Pursel, who is being held in the Black Hawk County Jail on two counts of murder in the first degree, to turn himself in now.

Pursel has not had a perfect record during the 31 years since he was first interviewed for the double homicide. He lived in the Waterloo area at the time of the murder, Pillack said, but for the last 15 or 20 years, he was living in South Gate, Calif.

"Before that, he was in prison [in California] for some type of sexual contact with an underage person," Pillack said.

The Huntbachs had two daughters and a son. Only one, daughter Barbara Beck, is still alive. A call from msnbc.com to Beck went unanswered on Friday. But Pillack said when he spoke with her on Thursday to share news of the confession, she was in a state of disbelief.

"She just wanted to make sure that we had the right person in jail," he said. "She wanted assurance that this wasn't going to continue on."

Pursel had an initial court appearance on Thursday, in which his $500,000 bond was increased to $1 million.

Pillack, who has worked for the Waterloo police department since 1979, said the 1981 double homicide was "a shock to community," and having Pursel turn himself in this many years later was totally unexpected.

"It's very unusual to have somebody confess to any crime, let alone a double homicide that happened 30 years ago," he said. "But we were happy to be able to say we solved the crime."
