OKLAHOMA CITY - Oklahoma City Police have linked an accused serial armed robber to four murders.

Police arrested Mario Normore, 27, in October 2017 for the armed robberies.

Only months after being released from prison, police said Normore went on an armed robbery spree through the metro. He has been charged for holding up two banks and eight businesses from August to October 2017.

Police said his violence did not end there.  

“Investigators have been able to link him to four murders, as well from 2017,” said Officer Megan Morgan, Oklahoma City Police Department.

Police said Normore is connected to the July 2017 murders of Bashar Burks and Ashley Easton. The man's remains were found in a burned car and Easton's body was discovered the following day in the same area.

Three months later investigators found another victim.

“The second incident is related to investigators locating the body of Searra Howe in a remote area of the 78 hundred block of North Oak Avenue,” said Morgan.

Meanwhile, police were investigating the October 2017 disappearance of James Knowles. His roommate at the time ran to the store and has not seen Knowles since.

“I was only gone for probably two or three minutes,” said Quiana McCloud, witness. “I come back and he’s gone. His keys are there, his cell phone there, the doors unlocked and that’s not like him.”

McCloud said Knowles was like a father to her and the man accused of murdering him was a neighbor.

She remembers asking Normore if he had seen Knowles.

“And he was like no my girlfriend is missing too,” said McCloud. “Gave me this whole story how my dad and his girlfriend were missing together.”

Police said in all the murder cases, Normore knew the victims.

McCloud is now asking Normore to lead police to the missing man.  

“Tell us where he is,” said McCloud. “So we can put him to rest and have peace.”
