Man Accused in Fatal Punk Rock Show Stabbing Set for Court Appearance

A 21-year-old man accused of fatally stabbing another man in a punk rock show mosh pit in Santa Ana last week was set to be arraigned Tuesday on a murder charge, prosecutors said.

Juan Angel Rivera, a Santa Ana resident, was charged with one count of murder with a sentencing enhancement that he used a knife in the attack, according to the Orange County District Attorney's Office.

Prosecutors said Rivera stabbed 23-year-old Nathan Joe Alfaro multiple times in the torso during an altercation at the concert at Underground DTSA last Thursday night.

The victim's friends said one man in the crowd had gotten rowdy and started pushing people trying to start a mosh pit. When the melee was broken up, there was blood on the ground and they realized Alfaro had been stabbed. Alfaro stumbled outside to the sidewalk and collapsed.

Rivera was arrested the following morning.

Alfaro, of Westminster, worked part time as a cashier in the cafeteria at Golden West College and was at the club to see a friend's band play, friends said.
