The Santa Clara County Sheriff's office released the name of the man who was shot and killed by Fremont SWAT officers in Cupertino Sunday.
He has been identified as 34-year-old Sonny Lopez.
Police say they had an arrest warrant in hand and were on a SWAT stake out in Cupertino Sunday morning after learning Lopez was inside an apartment complex on Miller Avenue.
Investigators said Lopez walked outside just after 2 p.m. They say after they approached him in full tactical gear and identified themselves as police, he ran off.
Police spokesman Bill Veteran said the officers fatally shot Lopez about a block away.
They said he was armed with a pistol, but did not immediately say whether he fired it. They said Monday that fact is still part of the investigation.
Police say the man shot and killed his uncle, Larry Lopez last Monday. Lopez, 49, was found dead inside his Sycamore Street home by his son.
He is also a suspect in a brutal attack of an elderly Saratoga man and his daughter. The two were beaten inside their hilltop home back in December. Police said 94-year-old Charlie Maridon initially survived the attack, but later died of his injuries. His 64-year-old daughter was also beaten, but survived.
The motive for the Saratoga attacks was robbery, according to police. Police did not say what motivate Lopez to kill his uncle.
