"You have the same question I had this morning: How could this occur?" Colbert said. "What did [Guardian Services] know about the son, and is it logical that they would allow him to take her out?"
Guardian Services provides assistance to older adults in the Philadelphia suburbs who are "unable to manage personal and financial affairs," according to its Web site. Company officials have not returned several phone calls from the Daily News seeking comment.
Steve Molin, 58, a self-employed contractor with a history of bizarre behavior, told police that his mother accidentally fell out of his moving vehicle shortly before midnight Tuesday while driving on Carey Road in Berlin, Md. He said he backed up after she fell.
"It was just an accident," he told a judge Thursday, according to the Maryland Coast Dispatch. "She suffered from Alzheimer's and was playing with the windows."
But Detective Cpl. Mike Lupiwok, of the Worcester County Sheriff's Office, said investigators concluded that she had been run over two or three times. "The investigation showed it was intentional," he said.
Colbert said that he was legally prohibited from discussing why Emily Molin had been a COSA client. Police and neighbors in Darby, where both Molins had lived for years, say their house on Summit Street was packed with junk and trash and was, at times, uninhabitable.
Steve Molin has had numerous brushes with the law, including a harassment conviction in February. He once accidentally set fire to a local dentist's office while doing plumbing work, according to police. In 1993, he was charged with stalking a Willingboro woman when he showed up at her house on Valentine's Day, uninvited, with flowers, cherry cheesecake and a bag of red peppers.
But several Darby residents who know Molin say they can't believe he would murder his mother.
"I don't think he would do something like that intentionally," said Terrence McKinney, 30, who has worked with Molin. "It could have just been a freak accident. It must have been dark or something."
