Bail agent accused of murdering man who did not have an arrest warrant. Police say agents' mom helped.

A California bail agent shot and killed a man who did not have an active arrest warrant and cops now say the agent's mom helped in the murder. 

Police are trying to find the mom and issued a warrant for her arrest. 

On April 23, Fabian Herrera, 36, called Palm Springs Police Department and told them he was going to 33-year-old David Spann’s home to attempt to locate him, authorities said.

That incident turned deadly, as Spann was killed and Herrera was charged with his murder, police said.

Now, the Riverside County Sheriff’s Department announced that Lisa Vargas, 53, Herrera’s mother, was at the scene of the murder. Police say that she helped Herrera, but it is unclear how.

Lt. William Hutchinson with Palm Springs Police Department said, "Mr. Spann was wanted by a bail agency for violating terms of his bail. He was not wanted by the courts, he was not wanted by law enforcement and there was no warrant out for his arrest."

KESQ reported a timeline of the incident, which Hutchinson gave and the incident started around 2:10 a.m. with Spann calling to say someone was trying to break into his home and they could hear yelling in the background. 

At 2:13 a.m., police said the Ring alarm company for Spann’s home called the dispatch center to report that a panic alarm had been triggered at Spann’s home.

Around 2:15 a.m., the sergeant who spoke with Herrera earlier on heard about the activity going on at Spann’s home, so he called Herrera, but the bail agent did not answer, according to police.

Two minutes later, Herrera calls the sergeant back and says he needed immediate help and officers were dispatched at that time, police said. At 2:18 a.m., Herrera told the sergeant that Spann was armed, but the bail agent had the suspect held at gunpoint, authorities noted. 

At 2:20 a.m., cops arrived and seconds later reported that shots were fired. Police say Herrera pulled the trigger and officers tried to provide aid to the victim. 

Herrera was charged with murder and being a felon while in possession of a firearm, according to police.

He pled not guilty to all charges on April 30, authorities said.

Since then, investigators from Riverside County Sheriff’s Department learned a second person assisted Herrera when the shooting happened, police said.

Vargas was identified as being that helper and she is not a licensed bail agent, authorities said. Investigators issued a warrant for her arrest for her involvement in this incident.
