Man starts serving life sentence for murder

A 42-year-old Chickasha man has arrived at Lexington Correctional Facility to begin serving a life sentence for the May stabbing death of an Anadarko man in rural Caddo County.

Court records show Mark Edward Connelly arrived at the prison Friday. He pleaded guilty to first-degree murder on Oct. 30 and received a life sentence without parole and no credit for time served. 

Connelly stabbed David Roberts, 34, to death while on a drive in rural Caddo County last summer. Investigators found Roberts slumped over inside a vehicle with several stab wounds to the head and neck and a portion of the weapon embedded in his chest.

District Attorney Jason Hicks has called Roberts' murder "an extremely violent attack" and said it happened while they were high on drugs. 

A Caddo County deputy found a bloody Roberts slumped over the middle arm rest in the front passenger seat when he went to investigate a report of a stabbing on May 22, 2013.

Caddo County Undersheriff Lennis Miller later found Connelly and Shayla Jackson walking along the road about a quarter-mile north of Roberts, and Jackson's clothes were covered in blood. Jackson told Miller that she, Roberts, Connelly and DeeAnna Carpenter had been driving down the road when some fictional Mexicans drove up and wanted to talk to Carpenter before stabbing Roberts.
