Police Arrive at Sunday Shooting 60 Seconds After ShotSpotter Alerts Them, Find Injured Woman

In the second incident in its first week on the job, Pasadena’s new ShotSpotter gunfire detection system sent officers to the scene of a shooting in the 1800 block of Navarro Ave. Sunday afternoon where they found an injured victim.

Shotspotter is automated technology that detects gunfire and instantly alerts police.

Pasadena police Lt. Monica Cuellar said a woman was cut on her forearm from car window glass shattered by a bullet during Sunday’s shooting.

The ShotSpotter system detected and immediately reported 18  gunshots at 1:54 p.m., Cuellar said. Officers on patrol were instantly notified and arrived at the scene of the shooting within 60 seconds.

Cuellar said little is known about what occurred because all three victims in the car struck by gunfire were uncooperative with investigators. No suspect or suspects have been identified as of this writing.

Investigators located seven shell casings and one bullet strike in a nearby home, Cuellar said. 

Video from nearby home security systems is also being examined, she said.

The ShotSpotter gunfire triangulation system went into service last Monday. Since it was activated it has alerted police to two shootings.

The first occurred Friday evening on Highland Street when the system confirmed a single gunshot was recorded.  Police said they never received any 911 calls about the incident.

Field officers received the ShotSpotter alert on their devices and self-dispatched simultaneously with the Police Dept.’s Dispatch center receiving the alert.  A single gunshot was detected at 6:23 p.m and officers were at the location at 6:24 p.m., according to Lt. William Grisafe.

In that case, Grisafe said, no evidence of the shooting was found. Local hospitals were contacted by no gunshot victims were located.
