Police say one man has been arrested after an attack on family members, followed by a manhunt that shut down a portion of State 77 for about two hours Wednesday morning.

GREENHEAD — One man has been arrested after a violent altercation and manhunt that shut down a portion of State 77 for about two hours Wednesday morning.

The Washington County Sheriff's Office responded about 2:30 a.m. to a call from a juvenile that a man had "hit several people and was destroying the house," according to a WCSO news release. The dispatcher reported hearing several gunshots fired during the 911 call.

While the caller and a younger sibling hid in a closet, a second 911 call came in, identifying the man as Christopher Reinhardt, 35, of Chipley. The caller, Reinhardt's mother, said Reinhardt had shown up at his grandmother's house, 5728 State 77, and began to physically attack her, then retrieved two handguns. The mother also reported heading gunshots.

Reinhardt then fled the home on foot, prompting a shutdown of northbound traffic on State 77 at 4:20 a.m. WCSO, along with the Bay County Sheriff's Office and K-9 units from Holmes Correctional Institute and the Northwest Florida Reception Center, eventually located him and booked him into the Washington County Jail.

He is charged with three counts of aggravated assault with a deadly weapon without intent to kill, battery on a person 65 years of age or older, two counts of cruelty toward a child that could result in physical or mental injury, and battery touch or strike.

Both Reinhardt's mother and grandmother told police Reinhardt had threatened to kill them, WCSO reported.

"The safety of all our citizens is a priority, but the moment a child is involved, all resources are utilized as much as possible,” WCSO Sheriff Kevin Crews said in the news release.

The highway was reopened at 6:40 a.m.

Anyone with information on this or any other case is asked to call WCSO at 850-638-6111 or contact Crime Stoppers at 850-638-TIPS (8477) or tips@wcso.us.
