It was supposed to be a night celebrating a friend's birthday, but the party on May 3rd at the Pied Piper in Sacramento quickly changed after an argument with a stranger.
"Isaac and Mr. Watkins got in an argument inside the bar. Other people went outside where James Watkins was and he ended up being shot outside," said a witness at the scene.
James Watkins died days after the shooting. Isaac Rivera was arrested and charged with his death, but those charges changed and were reduced to assault with a deadly weapon days before Rivera's trial started in October.
According to Rivera's attorney, forensic evidence revealed that the bullet found inside Watkins didn't match the gun Rivera was carrying.
On Thursday, Rivera's trial came to an end with a hung jury. As the day unfolded investigators got an arrest warrant for Israel Dinnocenzo for his alleged involvement in Watkins' death.
He led authorities on a chase Thursday night and was later caught in Elk Grove. The 21-year-old suspect is now charged with Watkins' murder.
"He was a person we identified in the beginning of the investigation at that point there wasn't enough probable cause to arrest him," said Sacramento County Sheriff's Department spokesperson Tony Turnbull.
Turnbull said both Rivera and Dinnocenzo are believed to have shot at Watkins.
Rivera's legal team said he could still face charges from assault with a deadly weapon to murder. The Sacramento District Attorney's office will make that decision on how to move forward.
