A 31-year-old man has been identified as the suspect in a violent crime spree that left three dead and three others hurt in the South Bay, police said.
The suspect, identified as Kevin Parkourana, was arrested in connection to Thursday's carjacking and stabbings in San Jose and Milpitas.
San Jose police Chief Anthony Mata in a news briefing Friday afternoon said the crime spree were random, senseless attacks. Parkourana is being held in Santa Clara County jail and is charged with multiple counts of homicide, attempted homicide and carjacking, the chief said. Mata also said Parkourana was on active probation when he was arrested.
Police on Friday also said they still do not have a motive.
Suspect in crime spree has extensive criminal history
Court documents show Parkourana has been convicted of felony vandalism, felony possession of a dagger, and for being in possession of an explosive device - a pipe bomb. He also has spent time in mental court, according to the documents.
"We're part of the system. We have to see where the system failed this individual," Mata said.
Parkourana lives in a duplex on Kooser Road in San Jose. No one answered the door when an NBC Bay Area crew knocked on Friday.

Neighbor Tristan Estes said it is heartbreaking to hear of Parkourana's reported arrest after the suspected attacks because it was no secret he was known to be unstable.
Timeline of attacks in deadly South Bay crime spree
The attacks began shortly after 3 p.m. Thursday in San Jose.
Police said Parkourana first carjacked and stabbed a victim near his home on Kooser Road. He was then responsible for another stabbing and attempted carjacking in a parking lot near Hillsdale Avenue, police said.
Another stabbing was reported minutes later on 10th and Santa Clara streets. Then blocks away at 16th and Santa Clara streets, police said Parkourana intentionally ran down an elderly couple. The couple died from their injuries.
Parkourana is then accused of hitting a person on a scooter with a vehicle in the same area. He then traveled to Milpitas, where he fatally stabbed one more person in a Smart & Final parking lot before finally being arrested by Milpitas police.
