Katie Holmes’s brother-in-law, Joseph Jeffrey Fretti, 48, died April 12 after being found unconscious in his parents' home in Sarasota, Fla.

Police arrived at the scene at 7:53 p.m. that Sunday after a 911 call. Fretti was unconscious and deemed to be in cardiac and respiratory arrest. An hour later, he was pronounced dead at The Doctor’s Hospital in Sarasota. An autopsy was not conclusive as to a cause of death. "We're still investigating," says Dr. Russell Vega of the Florida District 12 Medical Examiner’s Office. "There is no indication of foul play."

Fretti was separated from Holmes's sister Tamera, 41, who filed for divorce on Feb. 13. Tamera had recently been granted temporary custody of the couple’s children, ages 10 and 6. The couple, who had been married since 1995, own a funeral home near the Sylvania, Ohio home where Katie, 30, grew up.
