TULSA, Oklahoma - Police say two Muskogee brothers are dead following a shooting late Wednesday in a Tulsa shopping center.

Officers were called to the 5600 block of East Skelly Drive at 10:50 p.m.  They arrived to find 61-year-old Keith Williams and 53-year-old Glenn Williams dead next to their car from gunshot wounds.

Police say the brothers supervised cleaning crews at various businesses around Tulsa and had been called to a business by one of their crews on Skelly Drive to check out a suspicious vehicle parked nearby.

Officers say both men were walking toward the car when someone inside the vehicle shot both men then drove away. Both died at the scene.

Police are trying to learn more about the shooter and find out if anyone else was inside the vehicle.

"We have some information, suspect information, leads. I'm not at liberty to discuss what that information is at this time," said Captain Malcolm Wightman.

Tulsa Police say the brothers are the city's 36th and 37th homicides of 2018.
