Suspect Arrested for Murder

On Monday, May 3, 2021 at about 11:50 pm, the San Rafael Police Department received a 911 call from a subject who said that he was on Windward Way in San Rafael and saw a person that appeared to have been shot and that person was unresponsive and lying on the ground. 

SRPD Units responded to the area and found a 23-year-old male, later identified as Wilmer Gonzalez Velasquez, deceased next to a vehicle.  It appeared Velasquez had been shot at least once. 

SRPD Detectives were called in to conduct a homicide investigation and learned the following:

Velasquez was in a vehicle on Windward Way with two other people.  Velasquez was in the right front passenger seat and the suspect, Jeffrey Osmaldo Aguirre, a 19-year-old resident of Novato and Conroe, Texas, was seated directly behind Velasquez in the right rear of the vehicle.  While the vehicle was in motion, the driver of the vehicle heard a loud bang and immediately pulled to the right curb of Windward Way.  He saw that Velasquez had been shot by Aguirre and was asked by Aguirre to help him.  The driver refused to help and was threatened by Aguirre but was able to get out of the car and run from the area.  Aguirre fled the area in an unknown direction.

Numerous witnesses were interviewed, and the investigation continued into the next day.  SRPD detectives learned that Aguirre recently came back out to Marin County from Conroe, Texas.  Aguirre has family in the area and was a previous resident of Novato.  Information was developed that Aguirre was possibly at a residence in the 400 block of Maine Avenue, Richmond. 

SRPD Detectives were assisted by the Marin County Sheriff’s Office Special Investigations Unit in Richmond.  An arrest warrant/search warrant was obtained for the residence and the San Rafael/Novato Crisis Response Unit (SWAT and Hostage Negotiations) executed the warrant in Richmond.  Aguirre was located and peacefully surrendered. 

Aguirre was transported back to San Rafael where he was interviewed by Detectives.  After the interview, He was booked at the Marin County Jail for 187 PC-Murder.

Anyone with information about this crime is asked to call San Rafael Police at (415) 485-3000. Tips can also be made online at
