TECUMSEH, Oklahoma - Two men considered armed and dangerous remain on the run after a deadly shooing Saturday in Tecumseh.

Police say suspect Shane Pitts and Justin Moore could be "carrying military-style assault rifles" following the drive-by shooting that killed one person and injured several others.

Keevin Dixson was in the car at the time of the shooting. He says he believes he and his friend David Woods were the targets, but it was his girlfriend of eight years, Andrea Hollis, who was killed.

"Life of the party, anywhere you went, she'd light up the place," Dixson said. "It wasn't her time to go."

Dixson is still in disbelief over the loss of his girlfriend, 27-year-old Andrea Hollis.

"We were sitting right there," he said, pointing toward the end of the driveway.

Dixson says he, Andrea, and friends, David Woods and Leslie Kent were pulling out of the driveway of the Tecumseh home where Andrea lived, when they were confronted by Pitts and Moore. He says Pitts had an assault rifle in his hand.

"I said ‘what, you gonna shoot it?'" Dixson recalls. "Bout that time, pop, pop, pop, pop."

Investigators say nearly 12 rounds hit the car, injuring Woods and Kent and killing Andrea.

"I loved her," Christy Hollis, Andrea Hollis' mother, said. "She's my only girl."

Hollis said her daughter knew the suspects.

"Apparently, he's gone crazy," she said. "He's still on the loose and the police are looking for him and his friend that did this and we want them arrested."

But Dixon said the shooting stems from a long history of violence between the suspects and Woods and himself; bad blood that resulted in the death of an innocent bystander.

"This is injustice. I mean he just opened rounds," family friend Megan Daniels said. "I mean, she's 27 years old; that's way too young. She's way too beautiful to be taken out like that."

At last check, Woods was in critical condition and said to be stable at OU Medical Center. Kent was treated and released. Investigators say on Sunday they executed a search warrant at Pitts' house in Wanette and recovered some evidence in the case.

Meanwhile, investigators need help in finding the pair. They are believed to be traveling in a 2008, dark-colored GMC Sierra truck with Oklahoma plates 617-FCF with a PBR rodeo sticker and 20-inch RockStar rims. 

If you see it, or know the whereabouts of the suspects, call 911 or contact the Pottawatomie County Sheriff's Office directly at (405) 273-1727.
