SAN JOSE — A man in his 30s was chasing a person who had just robbed him on the street when the other man suddenly turned and shot him to death, authorities said.

The frenzied sequence was reported about 10:04 p.m. Thursday near Sherman and Willow streets south of downtown San Jose, according to San Jose police. The victim was later pronounced dead at the scene. He was not immediately identified.

Suspect information was not publicly released, but police sources said an adult male robbed the victim before the deadly confrontation. No arrest had been made as of Friday afternoon.

The slaying is the 29th homicide of the year in San Jose and the second in four days: Sunday, a 22-year-old Oakland man was stabbed to death a couple of blocks away at Second and Martha streets.

San Jose is currently on pace to reach its highest homicide total since 1991, when 53 were recorded. At the same point in 2015, 16 homicides had been recorded on the way to a yearlong total of 30, which was the lowest in five years.
