DEARBORN HEIGHTS, Mich. – Details are emerging about the man shot and killed Thursday inside the Dearborn Heights Police Department after he threatened a security guard with a knife.
Mark David Henning, 48, was at the Dearborn Heights Justice Center for a misdemeanor drug charge cited Nov. 28 and a warrant was requested. He hadn’t been arrested on drug charges since 1988.
Henning was going through a security point when an altercation broke out between him and a security guard. Henning lunged at the guard and was shot.
Witnesses said his brother, who was with him, yelled out that Henning was high on cocaine at the time of the attack.
Neighbors said Henning was born and raised in a home on Carole Lane in Dearborn Heights. After he his parents died, he lived there with his own family.
“My kids would always go over and play with them because they had a trampoline,” a neighbor said.
Henning had a son and two daughters.
Since his divorce about five years ago, Henning started spiraling out of control, according to the neighbors. The house fell into disrepair and they had seen teenagers coming and going at all hours of the day.
“Real neighborly,” a neighbor said. “But after his wife left him, about a year later he started letting everything go.”
The medical examiner conducted the autopsy Friday and the results will not be available for six to eight weeks. Toxicology results are also pending.
