A 28-year-old man is at the center of a nationwide manhunt following accusations of him killing his girlfriend and shooting a female jogger in Mississippi last week.

Alex B. Deaton is also the person of interest in the murder of a 69-year-old woman, who officers found shot to death inside a church.

Highway Patrol officers said his last known location was in the Tulsa, Oklahoma area, WLBT-TV reported.

Deaton is considered to be “very dangerous” and may be armed with multiple handguns. The 28-year-old, who is now charged with first-degree murder and assault, had no criminal history prior to his alleged crime spree.

Sheriff Bryan Bailey told the Clarion-Ledger, “Something inside of him appears to have snapped.”

Deaton is accused of strangling his 30-year-old girlfriend, Heather Robinson, at an apartment in Rankin County, just east of Jackson. Officers found her body on Friday, Feb. 24. Earlier that morning, a female jogger told police a white man with facial hair shot her from his driver’s window. Police have not released the name of the jogger and her condition is unknown.
