ORLANDO, Fla. (AP) — The engineer accused of fatally shooting one employee and wounding five others at the firm where he once worked is "very mentally ill" and crumbled under the stress of his divorce, bankruptcy and unemployment, his attorney said Saturday.

Jason Rodriguez, 40, was ordered held without bail at the Orange County Jail, where he is under suicide watch after Friday's shooting. His mother, Ana Rodriguez, also apologized Saturday, telling reporters she is "so sorry for everything that has happened."

"Sorry for the families involved. I'm really very sorry, it is very hurtful," she said.

Public defender Bob Wesley asked the judge at a brief court appearance Saturday that police and prosecutors have no contact with Rodriguez without his permission.

Wesley told reporters that Rodriguez "is a very, very mentally ill person" who lost his emotional stability because of the deep financial problems he was having.

"This guy is a compilation of the front page of the entire year — unemployment, foreclosure, bankruptcy, divorce — all of the stresses," Wesley said. "He has been declining in mental health. There is no logic whatsoever, which points to a mental health case. It looks like a classic case of stress overload."

Employees at Reynolds, Smith and Hills recognized their former co-worker when he drew a handgun from a holster under his shirt, police said, and killed Otis Beckford, 26, next to a receptionist's desk in an office at a downtown Orlando tower. He then walked into the office and unloaded several more rounds, wounding five other employees at the company he had been fired from two years ago.

Rodriguez was taken into custody several hours after the shooting. He has been charged with first-degree murder.

Police said Rodriguez told detectives he blamed the firm for recent trouble he had receiving unemployment benefits. As officers led him handcuffed into a police station Friday, a reporter asked him why he had attacked his former colleagues.

"Because they left me to rot," said Rodriguez, who recently told a bankruptcy judge he was making less than $30,000 a year at a Subway sandwich shop and had debts of nearly $90,000. He is the divorced father of a young son.

All the victims worked at Reynolds, Smith and Hills, where Rodriguez was an entry-level engineer for 11 months before he was fired in June 2007, the company said.

Beckford was hit by at least two bullets. The gunman then went into the common work area and opened fire on his other victims. The Orlando Sentinel reported that Beckford had a young daughter and a fiancee.
