Alum: Suspect in killings, face-biting wouldn't 'hurt a fly'

(AP) — A 19-year-old Florida State University student with no criminal record fatally stabbed a couple at random outside their house, wounded their neighbor and was biting the dead man's face when deputies finally subdued him, authorities said Tuesday.

Martin County Sheriff William Snyder told reporters that Austin Harrouff, a former high school football defensive lineman and wrestler, may have been on hallucinogenic drugs when he attacked Michelle Mishcon, 53, and John Stevens, 59, at their Tequesta home late Monday.

Snyder said Harrouff stormed out of the nearby Duffy's, a popular sports bar and restaurant, at about 8:30 p.m. He said the would-be rescuer, identified by family as 47-year-old Jeff Fisher, called 911 at 9:20 p.m. to report the attack, which apparently began in the garage where the couple liked to sit at night.

A sophomore majoring in exercise science, Harrouff is muscular — rosters from Suncoast Community High School in nearby Riviera Beach listed him at 6-feet-tall and 200 pounds.

The coaches would always try to get him mad and play angry, and he never had it in him.

Flakka had a brief burst in popularity in late 2014 and 2015, primarily in South Florida, but its usage quickly waned after stories circulated about users' deaths and mental breakdowns, and a crackdown was carried out in China, where it has been manufactured.
