King County Prosecutors last week charged three alleged gang members with conspiracy to commit murder for a plot to kill three members of a rival gang who had allegedly assaulted them March 15 at a bus stop in Auburn.

Gregory J. Bolduc, 19, Brian Cortes, 18, and a 15-year-old defendant are each charged with one count of conspiracy to commit murder in the first degree.

Prosecutors also charged a fourth defendant, Ricardo P. Martinez-Perez, 18, with three counts of unlawful possession of a firearm in the second degree for allegedly providing weapons for the murder scheme, which they allegedly began planning the day after two of them were assaulted at the bus stop at Eighth Street Northeast and Harvey Road.

A police informant notified police about the plan.

Police interceded, took away weapons and arrested the youths.

Prosecutors will ask to prosecute the juvenile defendant as an adult. The hearing on that matter was at 10 a.m. Tuesday in Juvenile Court. The other defendants was arraigned at 9 a.m. Tuesday in courtroom GA of the Norm Maleng Regional Justice Center in Kent.

If prosecutors convict Martinez-Perez of three counts of unlawful possession of a firearm second degree, he faces a sentence range of 4 to 12 months in jail.

All four defendants are in custody.
