A 45-year-old active-duty Marine is being questioned in connection with the disappearance of a 22-year-old woman. KNSD's Monica Dean reports.
FALLBROOK, Calif. -- A Camp Pendleton Marine was on his way home from Afghanistan Tuesday as San Diego County deputies investigated the disappearance of his wife, Brittany Killgore, who was divorcing him.
"Thank you everyone for the prayers and concerns," Killgore's husband, Cory Killgore, a motor transport operator, said on his Facebook page. "I request you pray for her more then you do for me I have family and friends for support she is alone where ever she is."
Brittany Killgore's parents flew to San Diego from their home in Erie, Pa., Monday, according to media reports.
A person of interest who deputies said was “uncooperative” in the case was jailed over the weekend on a separate charge. Louis Ray Perez, 45, also a Marine based at Camp Pendleton, was last seen with Killgore, 22, who was dressed in a purple evening gown, officials told NBCSanDiego.com.
Sheriff’s Lt. Larry Nesbit said Perez was arrested Sunday on suspicion of possessing an AR-15 rifle stolen from the base. Investigators discovered the weapon in Perez’s car while they searched it for clues in Killgore’s disappearance, NBCSanDiego.com reported. He was being held at a San Diego jail on $500,000 bail on suspicion of illegal possession of an assault weapon and receiving stolen property.

"There is a strong likelihood Brittany is the victim of foul play," Nesbit said.

Brittany Dawn Killgore, 22, was reported missing Saturday.
Teams searching for Killgore scoured rural areas around Fallbrook on Monday.
They suspended their search in the large and dense De Luz Canyon Tuesday after finding nothing Monday, sheriff's spokeswoman Jan Caldwell told msnbc.com. She said deputies were following other leads, but she could not comment further because of the "very active" nature of the case.
Her cellphone was found about 60 miles south Saturday in San Diego's Gaslamp District by city trolley security.
Authorities, however, said they doubt Killgore ever made it to the shopping and entertainment district known for its nightlife. She likely never left the Fallbrook area, officials said.
The North County Times said records show Killgore filed for divorce last week from her husband, who officials said is returning from Afghanistan because of the disappearance but is not suspected of being involved. He was deployed last fall.
The San Diego Union Tribune said the couple, from Missouri, married in 2010 and moved to Fallbrook a month later. They lived in an apartment near Camp Pendleton gates.

The divorce was news to neighbor Christopher Oglesby, who told NBCSanDiego.com that Killgore was very nice.
“There’s nothing shady going on around here,” he said.
Another neighbor, Paul Burshteyn, told NBCSanDiego.com that Killgore could still return.
“Hope never dies,” he said.
Killgore is 5 feet, 7 inches tall, 130 pounds, and has brown hair and brown eyes, officials said.

Talk about an unhappy homecoming for an American Warrior. At least he won't have protesters, like the Vietnam Vets did. I hope she is O.K. and he gets help with dealing with his loss, (if she isn't O.K., or if she divorces him).
This case is interesting. I have a feeling her boy friend did something he shouldn't have and she paid the price. (Senseless). What I don't like about it is she was divorcing him while he was over seas. A fellow puts his life on the line and just then is when this woman decides to call it quits. As if he didn't have enough to worry about. Well, we'll see how this comes out if MSNBC bothers to print the conclusion.
I hope Brittany is alive and well, although per this story that is unlikely.
To Cory; Keep the faith. Hope she returns healthy and well. Try to work through this time in your lives with her. She and you are both young. You have a dangerous job, and she was lonely and wants her man by her side. That's hard when you're 10,000 miles apart.
what a coincidence..... She was divorcing him...hmmmm. Murder for hire anyone ?
Damn good thing for her husband that he was deployed out of the country or they would be pinning this on him. Cops usually go for the easiest target, and he would be it. Too bad cops.
Well, I am sure the cops are looking at the husband. What a coincidence that this young woman filed from divorce from her husband and the next thing you know another marine is a suspect in her disappearance/death now. Hmmmmmm.
How terrible for her family to be going through this. She was just trying to get home to her family and start over. My thoughts and prayers go out to her family.
