Florida officials say a 49-year-old beat his parents with a crowbar, killing his 83-year-old mother.

The attack occurred Tuesday as Thomas and Delena Schneiders were on their way to church. Palm Beach County Sheriff's deputies report that 84-year-old Thomas Schneiders says he made it out alive by playing dead inside his Lake Worth house for hours.

The Palm Beach Post (http://pbpo.st/1Nw4Z33 ) reports that Thomas Schneiders II was diagnosed with schizophrenia seven months ago and had lived with his parents for five years.

According to a sheriff's office report, the son became angry with his parents because they'd scheduled a doctor's appointment for him.

The younger Schneiders was ordered held without bail. Lawyer Michael Salnic has declined to comment.

The father was treated and released from the hospital.
