MANATEE -- Investigators are awaiting the results of an autopsy to determine how a man and woman found dead in their Bradenton home Sunday died, according to the Manatee County Sheriff's Office.

The couple's adult special needs daughter was in the home, in the 4900 block of 20th Street Court East, when the bodies were found by the couple's nephew, Jerry Alsup. Deputies arrived on the scene about 7 p.m.

No foul play is suspected, said sheriff's office spokesman Dave Bristow.

Bristow said William Krochmal, 48, and Dana Weaver, 55, had dealt with numerous medical issues.

Bristow said detectives are not sure how long the couple had been deceased.

Alsup, who works with his aunt, said he hadn't seen her since she left work early on Wednesday.

The couple's child, who was trying to wake the pair up for days, is now with a grandparent, according to Alsup.
