The Contra Costa District Attorney's Office has slapped an 18-year-old Oakley man, Sean Karp, with stern charges, including murder and firearm assault, in connection to the death of a 16-year-old at a party in October. Karp now faces legal action after allegedly firing the shots that killed Ke'Marion Tucker and injured three others.

With scrutiny intensifying, the Superior Court in Martinez witnessed the filing of a somber complaint today. In a grim twist, the charges leveled against Karp include one count of murder and an enhancement for the reported intentional discharge of his firearm. According to Contra Costa County officials, the three counts of assault with a semiautomatic firearm are laced with enhancements related to the use of the handgun and the resulting great bodily harm.

The incident that spurred the charges unfolded during what should have been celebratory moments at a residence party in Oakley. The joyous scene turns tragic as Karp is accused of opening fire, resulting in Tucker's death. In the chaotic aftermath, three other teens suffered injuries.

The investigation saw its share of turns before landing on Karp's doorstep. Initially detained by the Oakley Police on October 25, a different suspect in the shooting found himself in handcuffs, only to be released as detectives dug deeper, eventually pointing the finger at Karp. Assisted by the U.S. Marshals Service, Karp was swept up in a November 30 arrest in Brentwood.

With Sean Karp now firmly in the grip of the law, he resides at the Martinez Detention Facility, where he was scheduled for arraignment on December 6 at 1:30 p.m. The stakes are high, as reflected in his steep bail set at $2,660,000, promising a steep battle in court.
