SAN JOSE - The city experienced its first homicide in three weeks early Wednesday morning when a man was fatally stabbed at a homeless shelter, according to police.

It is San Jose's 26th homicide of the year, and the first since police rolled out a new gang/violent crime suppression effort on June 20.

Just after midnight police responded to the homeless shelter on West Julian Street after receiving a 911 call that a person had been stabbed, according to Sgt. Jason Dwyer. Officers say Christopher Bowman, who was living at the shelter, was stabbed during an altercation with another resident of the Julian Street Inn.

Bowman, 37, was pronounced dead at 12:25 a.m., Dwyer said.

Police arrested Matthew Jacobsen, 25, in connection with the homicide. He was still at the scene when officers arrived. Dwyer said the stabbing was not believed to be gang-related and the motive remains unknown.

Prior to this morning's stabbing, San Jose's last homicide happened on June 19, when 16-year-old Manuel Urzua was attacked by several gang members and shot at least once.
