ARDMORE, Okla. (KTEN) — Ardmore police are investigating whether four weekend shootings that left four people wounded could be linked.

The first gunfire was reported Friday night at 8:30 in the 700 block of Cottonwood Street NW.

"The suspect walked up to the front door and fired several rounds through the front door," said police Capt. Claude Henry in a written statement. No one was hurt and the two male suspects were seen leaving the scene in a gray and white hatchback.

About 30 minutes later, a woman was shot in the hip after answering the door at a residence in the 700 block of 2nd Avenue NE. 

Then at 9:30, a man was shot in the hip after coming to the door in the 4700 block of Travertine Drive NW. 

"After reviewing security videos ... the suspect fled the scene in a grey/white hatchback vehicle," Henry said.

On Saturday night, a man and a woman were shot in the 300 block of I Street NE at around 8 p.m.

"The suspect, who was the front seat passenger of a vehicle, fired nine to ten shots from the moving vehicle and then fled the scene," Henry said. The vehicle was described as a white four-door Honda.

Police did not disclose the names or conditions of the shooting victims. 

Ardmore police said the FBI is assisting in the investigation because Native Americans are involved. Anyone with information is asked to contact Detective Kevin Kropp at 580-221-2556.
