In a shocking incident at a recent metalcore concert in San Antonio, an altercation erupted among audience members, resulting in one man being accused of stabbing another multiple times. This event took place at the Paper Tiger venue, a popular location for live music, on the night of December 27. The violence disrupted the concert atmosphere, which was meant to be a night of energetic performances and community among fans of the metalcore genre.

Local news station KSAT reported that 36-year-old John Guerrero was apprehended and charged with aggravated assault with a deadly weapon. Allegedly, he stabbed a 21-year-old fellow concert-goer during the show. The incident raised significant concerns about safety at live music events, particularly in the heavy metal scene, which often attracts passionate but sometimes unruly audiences.

Law enforcement officials received a call shortly after 10 PM on that Friday evening. Responding officers discovered the victim just outside the venue’s entrance, suffering from multiple stab wounds. Emergency medical teams quickly transported the injured man to a local hospital, where he was reported to be in stable condition and expected to recover from his injuries.

The Paper Tiger was hosting a lineup of metalcore acts that night, with Life Cycles headlining the event. Other bands, including Fear of Loss, Voracious Contempt, Crossways 3000, and Public Threat, contributed to an exciting evening that was overshadowed by the violent outbreak.

Witnesses at the scene identified Guerrero as the alleged perpetrator of the attack. When he was taken into custody, he was reportedly still in possession of the knife used in the incident. This detail has raised further questions about security measures at live music venues, especially those catering to high-energy genres like metalcore.

Court records reveal that Guerrero was booked on Saturday morning, December 28, and subsequently released later that evening after posting a $100,000 bond. The incident has sparked discussions around the legal ramifications and the need for stricter safety protocols during such events.

Guerrero is scheduled to face a hearing regarding the charges on March 3, a date that many in the local music community are awaiting. A news report from KENS 5 detailing the incident can be viewed below, providing additional insights into this alarming situation.
