TAMPA, Fla. (WFLA) — A driver was stabbed after a three-vehicle crash Tuesday that shut down the Howard Frankland Bridge for several hours, according to the Florida Highway Patrol.

A 35-year-old man was stopped in the middle of the bridge for an unknown reason and appeared to be slumped over in his vehicle, troopers said. A 40-year-old man and his 43-year-old wife saw the man and stopped to help.

The couple couldn’t access the man’s car and the husband went to get something to break the man’s window, troopers said. However, the man woke up and crashed into the 40-year-old’s vehicle before backing up and trying to drive off.

While driving off, the 35-year-old man crashed into Patrick Douglas Scruggs, who was passing the incident, according to FHP.

Scruggs allegedly got out of his car, approached the 35-year-old man’s car, broke the window and stabbed him multiple times with a pocket knife, according to troopers. Scruggs reportedly tried to also attack the husband and wife, but they were able to get away uninjured.

A St. Petersburg police officer who was driving by stopped, detained Scruggs and assisted the 35-year-old, troopers said.

The 35-year-old was taken to a hospital with serious injuries but he’s expected to survive, FHP said. Scruggs was arrested and charged with aggravated battery, aggravated assault, and burglary of an occupied convenience.

The Howard Frankland Bridge was closed for about three hours.
