San Jose police went door to door and backyard to backyard Friday afternoon searching for a man who stabbed a woman to death near North First Street and Hedding Street Friday afternoon.
The stabbing was reported around 2:30 p.m. in a parking lot of a Togo's sandwich shop just east the the Santa Clara County Government Center.
Witnesses said the man walked up to the woman and started talking to her. The next thing they saw was the wounded woman on the ground. It was not clear if the two knew each other.
Togo's workers there said a customer ran into the store after seeing what was happening.
"She says lock the doors, lock the doors. And so we're like why? And she said there's a guy stabbing a girl. And so we get closer to the window. And you could see everything that's happening. And we couldn't do anything cause we could see the guy stabbing her," Togo's worker Jennifer Camacho said.
The victim was taken to a nearby hospital, but did not survive.
The suspect is believed to be an adult male. His motive was not known.
The yard-to-yard search failed to turn up a suspect, police said.
The woman's identity has not been released pending notification of her next of kin. Police would only say that she was 29 years old. A man who works in the area told NBC Bay Area he knew the woman and said she had a 10-year-old son.
Staff at Burnett Middle School, located at 850 N. Second St., were put on lockdown during the search, school officials said. Students at the school were already released for the day prior to the stabbing.
