A man died after being beaten and stabbed in a suspected domestic violence attack inside a residence in central Dublin on Friday night, according to city police.

Officers arrested the decedent's apparent girlfriend on suspicion of committing homicide and domestic assault, according to Dublin police Capt. Gurvinder Gosal.

The investigation unfolded just after 9 p.m. Friday when first responders were dispatched to a unit in the 5421 at Dublin Station apartment complex on Campbell Lane for a medical call reporting an unresponsive man, according to Gosal. The scene was just off Dublin Boulevard, a couple of blocks north of the Dublin-Pleasanton BART Station.

Police officers arrived to find Alameda County Fire Department personnel already on scene attempting life-saving measures on the man, who was subsequently pronounced dead. "The victim was found with injuries consistent with stab wounds and other blunt-force trauma," Gosal said.

Officers then contacted and detained a suspect, identified as 23-year-old Crystal Espinoza, whom investigators believe was in a dating relationship with the victim, according to Gosal.

"Based on evidence located at the scene and our ongoing investigation, Espinoza was placed under arrest for domestic assault and homicide. She was subsequently transported to Santa Rita Jail for booking," Gosal said.

The identity of the victim has not yet been released publicly, with family notification still pending, according to Gosal.
