A Detroit federal jury convicted the operator of an adult day care center and two home health care company owners in a $29 million Medicare fraud scheme, The Detroit Free Press reported on Thursday.

Felicar Williams, 51, Abdul Malik Al-Jumail, 54, and Jamella Al-Jumail, 25, were found guilty on Tuesday of billing Medicare for health services that weren't provided, according to the U.S. Justice Department. The conviction came after a 12-week trial.

Prosecutors say Abdul Malik Al-Jumail illegally paid Williams for submitting phony billing information on patients at Haven Adult Day Care Center. Al-Jumail used the information to bilk money out of Medicare through multiple health care companies.

Investigators discovered that Jamella Al-Jumail set falsified patient records on fire the day her father was arrested.

Psychiatrist Carey Vigor was charged, but was later acquitted, according to the Record - Eagle.
