6 innocent people, including unborn baby, killed during Southern California pursuits this week

Six innocent people, including an unborn baby, died in three separate pursuits throughout Orange and Los Angeles counties this week.

The most recent deadly chase happened in Pomona on Wednesday night. Marc Anthony Trejo and his pregnant girlfriend, Jennifer Alejandra Loera Zarco, died after a domestic violence suspect tried to get away from police on Garey Avenue. 

Zarco's due date was just a few days away.  

"It hits different when it's your own son and I really don't have the words for it, but I don't wish this on anybody," father Tony Trejo said. "They were so excited. They had plans, they had projects. They were both very artistic, Jennifer and Marc, and yeah... that's where the story ends."

Pomona PD said officers started chasing the suspect after he returned to the crime scene and intentionally crashed into a patrol car. 

Three other people were killed during police pursuits so far this week. 

On Monday morning, a woman in San Clemente died after a suspect in a stolen U-Haul van crashed into her SUV. Three other women were taken to the hospital in critical condition. 

In Anaheim, a 70-year-old man and a teenager died when a teen driver ran a red light early on Tuesday morning. Officers said it happened in a matter of seconds as they tried to pull over the suspect for erratic driving. 

Retired Pomona Police Department Sgt. Patrick O'Malley said each case differs, but that officers always prioritize the safety of innocent bystanders. 

Officers will consider several factors during a pursuit, including whether they can later locate and arrest the suspect, according to O'Malley. In the Pomona case, O'Malley said that officers had to weigh the costs of continuing the pursuit.

"But in a situation like the Pomona one, you make the call: It's too dangerous to continue, [then] he circles back around, and he kills everybody in the house. Now, whose fault is it?" O'Malley said. "The officers and the supervisors are trying to make these split-second decisions with the information that they have."

Attorney Dale Galipo has represented families of relatives who have been killed or injured during police chases. 

"If you really look at them case by case, some of the pursuits are totally unnecessary," Galipo said. "They're putting innocent members of the public at risk of being injured or killed."

O'Malley said departments across Southern California are constantly reviewing and adjusting their pursuit policies based on public safety.
