SALEM, Ore. (AP) — Two men have been indicted on murder charges in the shooting of a man found inside a crashed minivan near a Keizer shopping mall earlier this month.

Kristian Mann, 21, of Keizer, and Dasio Gonzalez, 21, of Salem, were initially arraigned Feb. 5 in Marion County Court on drug and gun charges.

Second-degree murder and first-degree robbery charges were added Thursday in an indictment filed by the Marion County Grand Jury, the Statesman Journal reported.

Gonzalez and Mann are accused of causing the death of Oscar Martinez while attempting to commit robbery, according to court documents. Mann’s indictment specifies a firearm was used in the crime.

Both are being held without bail. It wasn’t immediately known if they have lawyers.

On Feb. 3, Keizer police responded to a call about a crashed vehicle and found Oscar Martinez, 21, of Salem, dead inside.

According to the probable cause statement, Mann and Gonzalez were arrested a short time later and were each charged with felon in possession of a firearm and delivery of a controlled substance.
