OKLAHOMA CITY - Officers say robbers tied up a man in his own home then shot and killed him. Police say it's an unusual crime. Oklahoma City police have one suspect in custody, but they are still searching for a second suspect.

A search warrant was filed for one of the suspect's cars. Police say deputies arrested Gerald Jackson during a traffic stop three days after they believe he broke into a South Side home.

Neighbors say it used to be a peaceful neighborhood, but they say it has turned more violent in recent years.

Police say two men broke into a home in the 7900 block of South McKinley and tied up a man and two women before ransacking the place. Police believe the two suspects shot and killed 25-year-old Christopher Trevino.

A search warrant shows police believe evidence inside suspect Gerald Jackson's Chevy Impala will help further link Jackson to the crime. Police believe they will find the victim's property and the murder weapon inside the car. According to the search warrant, one of the female victims identified Jackson by a Facebook picture.

"Our investigators do believe that there is another person out there who is involved in this crime," Sgt. Jennifer Wardlow of the Oklahoma City police said. "We don't have an identity. We don't have a name on that person."

Neighbors say they would commonly see suspicious activity at the home but would not give details. No one in the neighborhood would individually go on the record by name.

If you have any information on the crime, the Oklahoma City Police Department urges you to call (405)-235-7300.
