The release from Placentia PD states that an adult male and female were pronounced dead at the scene, which Sergeant Connell confirms. He identified the victims as Alberto Vicente Lopez, 36, and Gregoria Ramirez, 65. According to the release, three adults and two children were hospitalized. Sergeant Connell says 10 people total were injured, and eight were transported to area hospitals for various injuries. One of the children was a 10-year-old girl, who was pronounced dead upon arriving to the Children's Health of Orange County, Sergeant Connell confirms. He identified the girl as Lucero Lopez, the stepdaughter of Alberto. The other child hospitalized was Lucero's younger brother. Lucero's mother — who is seven months pregnant with a baby girl, according to NBC Los Angeles — was taken to the hospital, Sergeant Connell tells PEOPLE. She is expected to survive, per KTLA. The passengers in the van — which was reportedly driven by their church pastor — were on their way home from a Bible study at the Vida Nueva Church, NBC Los Angeles reported. Sergeant Connell says the suspect is Mario Armando Paz Jr., who witnesses reported running a red light before hitting the van. However, Sergeant Connell tells PEOPLE that the cause of the collision is still under investigation. Paz Jr. was arrested at the scene and booked on suspicion of a felony DUI and gross vehicular manslaughter, Sergeant Connell tells PEOPLE. Paz Jr. is set to appear in court Friday. It is unclear if he has retained an attorney to comment on his behalf.
