Investigators say they're waiting to question a man who was shot in a Lawton parking lot, during an incident which ultimately claimed two other lives.

Lawton Police Captain Craig Akard says 29-year-old Latesha Pettaway was shot to death Sunday night, at Thunderbird Lanes bowling alley on Cache Road. 

Her brother, 23-year-old Shannon Taylor, was also shot. Akard says Taylor's being treated at an Oklahoma City hospital.

"It's not life-threatening injuires," Akard told KTOK. "But from what I understand, they had to wire his jaw shut."

Akard says after Pettaway and Taylor were shot, 24-year-old Ricky McDaniel apparently shot himself at another location. Akard says McDaniel died Monday, at a Lawton hospital.

Police believe McDaniel was Pettaway's boyfriend.
