Abused Georgia teen found on streets of L.A. - Atlanta News, Weather, Traffic, and Sports | FOX 5

Police say a teenage boy found malnourished and confused at a California bus station had been locked up and starved for years in his metro Atlanta home.

An alert security guard and former Los Angeles police officer spotted Mitch Comer at a Los Angeles Greyhound bus station. Comer was described as confused, alone and looking much younger than his 18 years. Authorities said he was 5-foot-3 and weighed 87 pounds.

Comer didn't know the street, city or county he lived in because he'd been locked up inside that room for years.

"His father put him on a bus and told him that he was a man now, that he was 18 and he didn't ever want to see him again," said Cpl. Ashley Henson of the Paulding County Sheriff's Office.

Police have arrested the boy's father and mother, Paul and Shelia Comer. Both face charges of child cruelty and false imprisonment. Investigators say the couple kept Mitch locked up and barely fed him. He was last in school in the eighth grade, police said.

"An 18-year-old who weighs 90 some pounds, it's just horrific. It's just unbelievable to know all those times we were eating dinner having a good time, he's in there suffering," said Dion Walker, the Comer's next door neighbor. "Never knew they had a son, ever."

Walker's daughter played with the Comers' 11- and 13-year-old daughters, but because of their small size and weight, Walker says she thought they were years younger.

"Talk about feelings of guilt. As a parent, a neighbor, I just wish I had known. I wish I had seen some signs," said Walker.

Investigators say the teenage boy's sisters hadn't seen him in years and didn't even know the color of his hair even though they lived in the same home.

"They hadn't seen their brother in years, couldn't even tell you what color his hair was," said Henson.

Police are investigating whether the two younger girls were also abused. They said that it looks like the girls have never been in school.

The girls have been placed in state care.

Mitch Comer is legally an adult, but police have him in a foster home too.

"This is a situation where we would never, ever want to just release him onto the street because he doesn't have any street sense. He's been locked up in a room for years," said Henson.

Investigators say there has never been a police of child protective services call to the home before.

Paulding Sheriff's investigators, with the help of the Georgia Bureau of Investigation, plan to obtain a search warrant and carefully go through the family's home on Friday.
