He was being held for suspicion of animal cruelty in connection with the killing of two dogs on Saturday, police said.

While investigators did not officially connect the man to Sunday’s shootings, one weapon was recovered upon his arrest, police said.

The Los Angeles Police Department said leads led them to a tan or gold SUV that was located at a residence in the area of Polk Street and Kismet Avenue.

The man is possibly linked to a Sunday morning drive-by murder spree that occurred over the course of 60 minutes in San Fernando, Sylmar and Pacoima.

The third victim, described as a man in his 20s or 30s, was not identified.

Several others were also wounded in the shootings.
