Many of the victims were family members, including a teen mother and her 10-month-old baby boy.
TULARE COUNTY, Calif. (KFSN) -- Tulare County Sheriff Mike Boudreaux announced arrests have been made in the Goshen massacre.
Deputies executed three search warrants and arrested two gang members they say are responsible for the murders of six people, including a 10-month-old baby.
Sheriff Boudreaux says 35-year-old Angel Uriarte of Goshen and 25-year-old Noah Beard of Visalia are the shooters.
During the searches, Uriarte engaged in a gun battle with ATF agents, who ended up shooting him. He is undergoing surgery but is expected to survive.
Boudreaux says Beard was arrested without incident.
The following video below is surveillance footage from the house where the 6 family members were murdered. We advise viewers to watch at their own discretion.
Based on the evidence collected by detectives, it was determined two members of the family killed were Sureño gang members.
The two suspects arrested today were Norteño gang members. A motive is still unknown.
Detectives were also able to create a timeline of the killings.
Eladio Parraz was killed first, and Marcos Parraz was killed second. Next, Jennifer Anaya was shot in her sleep, and Rosa Parraz was shot as she was getting out of her bed.
Lastly, Alissa Parraz and her baby. Detectives determined Alissa heard the gunfire, grabbed her baby and exited the house.
She ran to the front fence, laid the baby on the other side and then jumped over herself. Detectives determined it was Beard who followed and shot both in the back of the heads.
