Seventy-nine year-old Henry Harvey and 22-year-old Zachary Hunt were both shot and killed. A customer called 911 after finding the two on the floor at the store at 13th & Oliver late Friday.
Both victims were shot multiple times, but police have not recovered a weapon.
Police say the suspect, 19-year-old Marquis Marshall, walked out of the store after the shooting. He was arrested without incident Sunday afternoon during a traffic stop at Second and Erie.
Police have reviewed surveillance video of the incident. They don't know how or if Marshall has any connection with the victims. Harvey was a customer in the store, Hunt was a clerk. Police tell us the two victims and the suspect were the only ones who witnessed the shooting. There were two other employees in the store, but they were in the back and didn't see what happened.
A 20-year-old relative was with Marshall during the traffic stop, that man was arrested and faces charges of aiding and abetting a felon.
Police say Marshall does have a criminal history. He's now in jail on a $1-million bond.
There have been 21 homicides in Wichita this year.
