San Jose: 2 killed, 4 wounded in shooting near SJSU On Thursday, police announced the arrests of 20-year-old Jesus Barragan-Sandoval, 18-year-old Raul Tellez and three boys ages 17, 16 and 15. All are residents of San Jose.

The victim — Cruz Antonio Castro, 20, of San Jose — was walking on the 10000 block of Lyndale Avenue about 6:50 p.m. on April 16, 2016, when the suspects got out of a car and opened fire, according to police.

A witness told this newspaper he heard people arguing, then a single gunshot. “Then I heard somebody say, ‘Just kill him.'” Three more shots were fired in quick succession, “like execution style.”

The witness said he saw a person sprint up the street and jump into the back of a car with its rear doors open.

Castro died later that night at a hospital, according to police. The homicide was the 12th of 47 recorded in 2016.

Homicide detectives were able to identify the five suspects after “extensive follow up,” according to Officer Albert Morales, a spokesman for the San Jose Police Department.

Tellez and the 16-year-old boy were arrested on Jan. 19, the 15-year-old boy on June 6, the 17-year-old boy on June 13 and Barragan-Sandoval on Monday. Police booked the two men into the Santa Clara County Main Jail and the three boys into Juvenile Hall on homicide charges.
