The Boston Red Sox line up during a tribute to victims of the Boston Marathon bombing and its aftermath, as an image of Massachusetts Institute of Technology Police Officer Sean Collier is displayed on the scoreboard, before a baseball game against the Kansas City Royals in Boston on Saturday.

Police officers lined streets in Boston on Saturday evening to honor Officer Sean Collier, who authorities say was killed by the Boston bombing suspects.

Collier’s body was released by the medical examiner’s office and taken to a funeral home in Stoneham, NBC station WHDH of Boston reported. Officers flocked to Albany Street to pay their respects as the hearse passed by, the station said.

Hundreds of people attended a candlelight vigil for Collier Saturday night at the town common in Wilmington. And the Boston Red Sox paid tribute to him and other victims of the Boston Marathon bombing and its aftermath before a game against the Kansas City Royals on Saturday.

Collier, 26, of Somerville, Mass., was an officer at the Massachusetts Institute of Technology. He was found shot in his vehicle on the campus late Thursday night as authorities pursued two brothers named as suspects in Monday's deadly marathon attack. One of the men was killed in a shootout with police and the other captured Friday night.

In a statement, Collier’s family said they were "heartbroken."

"Our only solace is that Sean died bravely doing what he committed his life to — serving and protecting others," the statement read.

In an MIT press release Friday, Police Chief John DiFava described Collier as "a dedicated officer who was extremely well liked by his colleagues and the MIT community."

Collier, who wasn't married, had been a patrol officer at MIT since Jan. 9, 2012, according to the university.

Collier's family asked for donations to be made in his name to The Jimmy Fund, which supports the Dana-Farber Cancer Institute in Boston.

A Long Island, New York, woman bought a BB gun, then drove her two children and another boy around and had them shoot at parked cars, police said.

Susan Becker, 43, of East Northport was arrested Friday, NBCNewYork.com reported.

Police said there were more than 60 reports of damage to car windows in the Islandia, Hauppage and Commack areas over the past two weeks, Newsday reported.

Police said Becker’s 13-year-old son and 15-year-old daughter and another 15-year-old boy were involved.

Becker was facing several charges, including endangering the welfare of a child, NBCNewYork.com reported.

News of her arrest came as a shock to one neighbor.

“Susan is a great mom, she’s a great neighbor, she’s always there to help everybody,” neighbor Susan Morelli told NBC 4 New York. “A very all-American typical mom. I just can’t say enough nice things about her because she’s just such a nice person.”

Morell said there must be some explanation “that we don’t know about. … She just wouldn’t do something like that.”

A search was due to resume Sunday for a 60-year-old hiker missing after two avalanches struck separate groups Saturday during heavy snowfall in the mountains near Snoqualmie Pass east of Seattle, a King County officials said.

In one incident, an avalanche struck three people on Granite Mountain near milepost 47 about five miles west of the pass along Interstate 90, leaving one missing and one injured, King County sheriff's Sgt. Katie Larson told NBC News. The slide carried the snowshoers about 1,000 feet, NBC station KING of Seattle reported. 

In the other incident, a slide hit a group of 12 snowshoers at an elevation of about 4,800 feet in an area north of the pass, KING reported.

Rescuers were bringing the group Saturday evening. A woman who was in the group told KING her survival instincts kicked in.

"Horrible experience, fear, avalanche came down like water ... water shape ... so we held onto trees and we survived," Kay Seo said.

KING reported that one man was buried up to his armpits and a woman with a dog was found after the dog led rescuers to her.

Snoqualmie Pass is along Interstate 90 about 50 miles east of Seattle. It is a popular skiing and snowshoeing destination in the winter and early spring.

The mountains in the region have been hit by spring snowfall in the past couple days, with the Alpental ski area at Snoqualmie Pass reporting about 11 inches of new snow. The Northwest Weather and Avalanche Center reported considerable avalanche danger above 4,000 feet and moderate danger below that level on Saturday, with the risk increasing in the afternoon.

The heavy snow and resulting vehicle accidents caused authorities to close westbound lanes of Interstate 90 over the pass Saturday night. 

The operators of an ambulance service illegally charged Medicare for more than $3.6 million in rides and services that patients didn’t need, according to a federal indictment in one of a series of similar cases out of the Philadelphia area.

Anna Mudrova, owner of Penn Choice Ambulance, and operators Yury Gerasyuk, Mikhail Vasserman, Irina Vasserman, Aleksandr Vasserman, Valeriy Davydchik and Khusen Akhmedov were charged with conspiracy to commit health care fraud, U.S. Attorney Zane David Memeger said in a statement. Other charges included making false statements, aggravated identity theft and money laundering.

According to the indictment (read it here in PDF), the defendants particularly targeted dialysis patients who needed multiple trips to doctor’s offices or medical centers each week but who did not require an ambulance to get there. The defendants are accused of paying kickbacks to patients or not collecting required co-payments, and of operating unsafe ambulances without required medical gear.

In one instance, according to the indictment, the patient rode in an ambulance’s front passenger seat and smoked cigarettes during the trip.

This is just the latest case of Medicare fraud involving bogus ambulance claims in the Philadelphia area, said Patty Hartman, spokesperson for the U.S. Attorney’s Office for the Eastern District of Pennsylvania.

A 37-year-old woman from Philadelphia was charged last week in a similar case involving more than $2 million in improper billing. And a couple days before that, two brothers pleaded guilty to 41 counts in another case. 

An Alaska State Troopers helicopter with three people on board crashed while on a night rescue mission and no survivors were found, authorities said Sunday.

About 10 p.m. Saturday, the helicopter, carrying a pilot and a trooper, picked up a snowmobiler who had been reported stranded near Talkeetna north of Anchorage, the State Troopers said in a dispatch. 

The pilot radioed that the copter was en route to meet medics, but it didn't arrive, the dispatch said. A search aircraft found the crash site about 9:30 a.m. Sunday but the dispatch said there were no survivors.

Identities of the dead were being withheld while authorities contacted family members, NBC station KTUU of Anchorage reported. The cause of the crash is under investigation.

"This tragedy is going to have a very profound effect on all the employees of the Department of Public Safety, the Alaska State Troopers, [and] the search and rescue community, " troopers spokeswoman Megan Peters told KTUU. "Helo-1 is our main helicopter that goes out, and Helo-1 has pulled so many people from the Alaska wilderness."

The snowmobiler had been stranded near Larson Lake, which is east of Talkeetna, about 90 miles north of Anchorage.

The helicopter was a Eurocopter AS350, built by Aerospatiale. Versions of the AS350 have been used in high-altitude rescues in the Himalaya, and one was able to touch down on the summit of Mount Everest in 2005.

Evan Spencer Ebel

The man suspected of killing Colorado's corrections chief may have been released from prison four years early because of a clerical mistake, NBC station KUSA of Denver reported late Friday.

KUSA said that court documents released by the state showed that Evan Ebel pleaded guilty to assaulting a prison guard while serving time for breaking into a car, having an illegal gun and carjacking a man. Under his plea agreement, KUSA said, Ebel's four-year term for assaulting the guard should have been served consecutively to the eight-year sentence he had been serving.

But the assault sentence was entered into a computer system as concurrent -- served at the same time, KUSA said. There's still a possibility that a judge changed the sentence, KUSA said:

Although the prosecutor in the Ebel's case does not specifically remember the sentence, he says it was his policy to never offer a concurrent sentence to someone already in prison.

If the judge changed the sentence, it's not reflected in the court minutes.

9Wants to Know is ordering a transcript of the court hearing to see what exactly the judge said during sentencing.

Ebel was freed in Jan. 28 after nearly eight years in prison. 

He is suspected of killing Tom Clements, executive director of the state Department of Corrections, on March 19. Clements was shot dead apparently after answering the doorbell at his home outside Colorado Springs.

Ebel is also suspected in the March 17 killing of a Domino’s pizza delivery man outside Denver. Authorities have speculated that Ebel used the man's uniform to get Clements to come to the door.

A Domino's uniform was found in the car Ebel was driving when he was killed in a shootout with deputies in Texas on March 21.
