CANTON — Police said Tuesday they believe more than one gunman was involved in the fatal shooting that left a northwest Canton man dead, his girlfriend in a hospital emergency room and a half-dozen “aggressive” pit bulls pulled from their home early Monday morning.

Anthony T. King, 26, suffered a fatal gunshot wound to the head, said Harry Campbell, chief investigator for the Stark County Coroner’s Office.

Detectives believe King and his 26-year-old girlfriend were shot in the first-floor bedroom of the home they shared in the 200 block of Fulton Road Northwest about 3:45 a.m. Monday, said city police Capt. Dave Davis.

Multiple shots were fired from outside the home by people presumably on foot, he said, adding that police believe there might have been more than one gunman.

Officers heading to the 900 block of Third Street Northwest to investigate a report that shots had been fired were flagged down on Fulton Drive by King’s girlfriend. She had sustained a gunshot wound to her arm, according to a news release Monday from the Police Department. The woman told police someone had fired several shots into her home.

Both shooting victims were taken to Aultman Hospital, where King was pronounced dead at 4:18 a.m., Campbell confirmed Tuesday.

The woman’s condition was not available Tuesday.

After the shooting, police called the Stark County Dog Warden’s Office to remove the six adult pit bills from the couple’s home. Davis said the dogs were removed for safe-keeping because both owners had been taken to the hospital.

Maj. C.J. Stantz of the Stark County Sheriff’s Office, which oversees the dog warden’s office, described the dogs as aggressive, adding they were being released to the Stark County Humane Society.

Davis said detectives continued to investigate the shooting Tuesday and said they did not have a motive or suspects.

“We don’t believe that this was a random incident,” he said.

He asked that anyone with information about the shooting call detectives at 330-489-3144 or leave a tip at the city’s TIP411 line by calling 847411 and leaving a message. The tip line can also be accessed through www.cantonohio.gov/police.
