OKLAHOMA CITY - Oklahoma County prosecutors have charged 21-year-old Gerald DeWayne Jackson with first-degree murder for the shooting death of Christopher Trevino.

Investigators said on January 15, Jackson and another man forced their way into a home in the 7900 block of S. McKinley Road. Trevino and two women were forced at gunpoint into a back bedroom, where they were tied up with electrical cords.

According to court documents, Jackson and his accomplice robbed the victims of jewelry, cash and other property. The two women said just before the suspects left, they shot a bound Trevino twice in the back of the head.

The two women were not seriously hurt. One of them later identified Jackson as one of the suspects after seeing his picture on Facebook.

U.S. Marshals arrested Jackson on January 19 during a traffic stop. He's now charged with one count of first-degree murder, one count of first-degree burglary, three counts of kidnapping, and two counts of robbery with a firearm.

He's being held without bond in the Oklahoma County Jail.

The second suspect has not been identified.
