SAN JOSE — Investigators are crediting a tip from the public with helping them locate and arrest a man suspected in a stabbing at a Willow Glen bar in November, according to San Jose police.

Joseph Hernandez, 29, of San Jose, was arrested April 2 on suspicion of attempted murder in connection with a Nov. 15 attack at The Willow Den bar on Lincoln Avenue, Sgt. Enrique Garcia said.

The stabbing was reported at 1:07 a.m. in front of the bar and reportedly stemmed from a confrontation inside. A sidewalk argument devolved into a fight, and then the stabbing, police said.

The suspect ran from the scene, and the victim, who was stabbed at least once, was treated at the hospital.

In mid-March, police publicly released photos and surveillance video of the fight, and late last month someone contacted police to identify the suspect shown in the images. Hernandez was arrested April 2 during a car stop by Officer Eric Bucholz.

Hernandez was also booked on suspicion of providing false identification — he allegedly lied to an officer about his name — and drug possession and had two arrest warrants related to domestic violence and drug possession.

Garcia said the tip was vital in solving the case.

“This is a prime example of the community working with media and the police,” he said. “We had exhausted all our leads. Then someone called in and gave us information, and investigators were able to make an arrest.”

Garcia said the stabbing arrest should encourage prospective tipsters who have information but might not be completely certain.

“We need people to call in any type of tip and let us determine what is good or bad,” Garcia said. “We can’t do everything on our own, and everyone’s going to benefit. In this case, community involvement was crucial.”
