Marquis Marshall is in custody in Pittsburg County.
They're questioning him in connection with a double shooting of two women in Tulsa at a home in the 400 block of East Latimer Friday morning.
Officers still want to talk to Marshall's cousin Dominic.
Investigators say the two men reportedly were at the home located in the 400 block of East Latimer Place at the time of the 2:20 a.m. shooting, but were not there when police arrived.
Inside the home, police found two women shot. EMSA took both to Tulsa hospitals. Police Sgt. Dave Walker says one victim was shot in the chest and she is in grave condition.
"From the door, you can see there's blood throughout the house so obviously, the victims were mobile inside," explained Sgt. Walker.
Police says both women are expected to recover.
