A Lancaster teen-ager held in the slaying of a Chatsworth High School student is expected to be tried as an adult, sheriff's officials said Friday.

Jason Jones is jailed at Sylmar Juvenile Hall in the Tuesday afternoon shooting that left Aaron Bruce Nathaniel dead outside a Chatsworth Carl's Jr.

``With the seriousness of the crime, undoubtedly he'll be tried as an adult,'' said Deputy Brad Foss of the Lancaster gang detail.

The determination of whether Jones will be tried as an adult will be made by a Juvenile Court judge after a fitness hearing, officials said.

Besides his suspected involvement in the fatal Chatsworth shooting, Jones is suspected of shooting at the Lancaster apartment of an ex-girlfriend.

``Our case will be put together with the LAPD (Los Angeles Police Department) case,'' Foss said. Officials said Jones, 17, and Cori Williams, 25, of Lancaster fired four or five shots Monday through a window of an apartment in the 43900 block of Bobby Jones Drive. Officials won't say which one they believe fired the shots; both were being held on suspicion of attempted murder.

Deputies said Jones pushed his ex-girlfriend to the ground, punched her, and kicked her in the head and torso. The girl was able to run into her apartment and close the door behind her.

``When the doors closed that's when the shots were fired,'' said Foss. ``She had visible injuries but did not require medical treatment.''

No one was hit by the bullets.

Jones was taken into custody shortly after the shooting in Chatsworth. Williams was taken into custody Wednesday.
