Four arrested in connection with attack on Crisanto Avenue

Extensive police work resulted in the arrest of four people associated with a violent attack on a man on Crisanto Avenue last week.

On Thursday, July 12 around 8:20 pm, officers responded to Rengstorff Park for reports of an assault. When we arrived, we met with a 16-year-old Mountain View resident who stated that while he was walking in the area of Ortega Park, people inside a Chrysler sedan as well as a Honda sedan attempted to attack him. The teen said then a short time later, while he was sitting with a family member in the parking lot of Rengstorff Park, a gray Honda drove up and a teenager jumped out, threatened the teen and then attempted to attack him. The car then drove off, and the teen went to a family member’s RV on Crisanto Avenue. There, the teen discovered blood inside and signs of another attack.

We learned through our investigation that a 19-year-old Sunnyvale man who had been inside the RV was currently at an area hospital receiving treatment for wounds that appeared to come from an assault. We responded to the hospital and there, learned the man was the one inside the vehicle when allegedly two males came in and hit him in the face multiple times with pistols. The victim suffered wounds to his face and hands as a result of the attack.

Mountain View patrol officers, along with detectives from the Crimes Against Persons Unit, the Crime Suppression Unit and the Gang Suppression Team, continued to look further into this incident.

On Saturday around 8:45 pm, officers were in the area of Rengstorff and Leland avenues investigating another possible call of a person with a gun when one of our officers saw one of the vehicles – the Chrysler -- associated to the attack two days prior. The officers conducted a high-risk car stop on the 2000 block of California Street and detained three people without incident – two 16-year-old Mountain View residents and 18-year-old Mountain View resident Cesar Rosas. Two guns were recovered from the Chrysler that matched those involved in the attack on Crisanto Avenue. 

One of the teens and Rosas, who were at that point identified as suspects in the assault case, were arrested for assault with a deadly weapon, burglary, brandishing a firearm, terrorist threats, carrying a concealed firearm in a car, carrying a loaded firearm in a vehicle in a public place, receiving stolen property and possessing high capacity magazines. Rosas is also facing gang enhancement charges.

The second teenager was arrested for carrying a concealed firearm in a car and carrying a loaded firearm in a vehicle in a public place. 

On Tuesday afternoon, 19-year-old Alberto Ibarra-Vallejo, who was also a suspect in the attack on the Sunnyvale man, was arrested on a warrant by Mountain View detectives on the 1000 block of Space Park Way. He is facing charges of assault with a deadly weapon, brandishing a firearm, as well as gang enhancement charges. 

 “This case was investigated tirelessly by patrol teams with incredible assistance by our Crimes Against Persons and our Crime Suppression units,” said Sgt. Alex Beraha. “These units, and this entire department, do not stop when it comes to protecting this city and its residents. It is long hours, and hard work. But without a doubt, we do all we can to bring those who would do harm to justice.”
