Throughout February 2021, Detectives from the Walnut Sheriff Station began to work closely with investigators from the Los Angeles County Sheriff’s Department’s (LASD), Major Crimes Bureau (MCB), Burglary-Robbery Task Force (BRTF), on a series of recent, Rowland Heights neighborhood robberies where suspects would follow the female Asian victims until the victims stopped and exited their vehicles. The suspects approached victims and violently pulled their purses away. The victims were knocked to the ground during these crimes. One of the robberies occurred inside the garage of a victim’s residence, where a victim’s family member was also accosted.

Investigators were able to identify a vehicle possibly used during these crimes as well as a possible suspect. On Thursday, February 25th, 2021, Investigators observed the suspect driving slowly through multiple business and retail areas in Rowland Heights. This behavior was consistent with the methods of the previous robberies in the area, in order to acquire a victim to follow. Deputies contacted the suspects in a parking lot of a grocery store. The driver was determined to be on active felony parole for a recent Burglary conviction and was ultimately arrested for multiple felony violations. The passenger was determined to be a 17 year old juvenile on active probation for robbery and possessed a concealed, stolen, loaded .40 Caliber semi-auto pistol. He was detained on multiple felony violations.
