CLEVELAND: A man who crashed his car on a Cleveland interstate, attacked people who stopped to help him and was killed by a sheriff’s deputy has been described as a prominent businessman.

The Cuyahoga County Medical Examiner’s Office says 33-year-old Brett Luengo died Thursday from a gunshot wound to the chest. Cuyahoga County Sheriff Clifford Pinkney said Friday the deputy used a stun gun on Luengo with no effect and then fired a single shot when Luengo lunged at him.

The deputy wasn’t injured.

Luengo’s family issued a statement Friday saying his behavior was “completely out of character.” Luengo was chief executive officer for a suburban construction management company he founded with his father.

Witnesses told Cleveland.com they saw Luengo attack several people who tried to help him after the crash.
