Suspect was biting off dead man’s face and grunting like an animal, after random killing of couple in Florida

Something made a young man go mad.

He viciously stabbed to death a married couple, and wounded a neighbour who tried to intervene, deputies said. They found him crouched over the bleeding corpse of the husband, biting chunks of his face off.

Martin County Sheriff William Snyder told reporters his deputies found the suspect late Monday in the driveway of a Palm Beach, Florida, home. Officers shot their stun guns at the 19-year-old multiple times to no avail. Even a police dog couldn’t get the man to release his victim.

Finally, three to four cops were able to wrench the suspect off the dead man. The man was “making animal noises,” and “grunting and growling” as officers yanked him away.

Inside the garage they found the dead man’s wife, also stabbed to death. Multiple “weapons of opportunity” were used to beat, slash and attack the couple, including a switchblade the suspect was known to carry. Officials said it looked like the husband tried to fight back.

Former North Miami Beach Mayor Jeffrey Mishcon identified the dead woman as his daughter, Michelle Mishcon Stevens, 53. Deputies identified her husband as John Stevens, 59.
