A week after four people died and many were injured in a deadly shooting in Stockton, California, investigators are still looking for a suspect and a motive. The San Joaquin County District Attorney's office has confirmed that a 22-year-old man named Luciano Guerrero, who attended the birthday party where the shooting took place, was later arrested for a "parole violation related to his presence" at the scene in Stockton. However, he is not a suspect in the shooting at this time, according to ABC 7.

What was meant to be a joyous celebration turned into a nightmare on the fateful day when someone entered the building along the 1900 block of Lucile Avenue and began shooting just before 6 pm. The people who were wounded range in age from 8 to around 30 years old.

Heather Brent, a spokesperson for the San Joaquin County sheriff's office, previously said that investigators believe it was a “targeted incident” at a banquet hall where 100 people or more had gathered for the party. “If you have surveillance footage, if you're a local business here, if you're in the area, live in the area, or maybe you've heard rumours — please contact the sheriff's office,” she added.
