ANTIOCH >> Less than two days after a shooting at a teen’s birthday party killed an 18-year-old girl and wounded six others, the city’s mayor drew a line from the “horrific incident” to the city’s beleagured police department, already operating far below capacity after multiple officers were placed on leave amid a racist-texting scandal.

On Monday, police released no new details about the shooting, which took place about 1 a.m. Sunday on Sunset Lane near Mountaire Park. The six people reported to be injured in the shooting were all expected to recover from the injuries, police said earlier.

It was not clear if the shooting took place inside the home where party was happening or outside the residence. Police said earlier that uninvited guests came to the party sometime before the gunfire started.

The city’s mayor, Lamar Thorpe, released a statement early Monday saying his “heart is with the victims and families” and insisting on swift change. Thorpe cited the Antioch department’s ongoing issues with staffing — compounded by the racist texting scandal, which has led to some 20 percent of the police force being suspended as authorities move through the disciplinary process.

“Each day these officers are on leave is another day we are prevented from having a stronger police presence on our streets to deter and/or respond to gun violence,” Thorpe added.

Authorities on Monday did not identify the 18-year-old girl who was killed, citing the investigation. She died at a hospital.

The six who were injured all were 20 years old or younger. They included one 18-year-old and one 20-year-old man, as well two 19-year-old and two 20-year-old women.

Police have not identified any suspects or persons of interest publicly.

“Birthdays are one of the most intimate and sacred celebrations in everyone’s life,” Thorpe said in his statement. “They represent growth, reflection and appreciation for life’s gifts. Over the weekend, one such celebration was cut short as a result of gun violence.”

Thorpe said he met with police Chief Steve Ford about the shooting and urged him again to fire the officers involved in a racist texting scandal that has gained national attention and shamed the department. For years, Antioch officers routinely used private text messaging groups to flaunt their racist views, spouting slurs in front of superiors without fear of reprisal.

The scandal has involved a total of 44 officers, about half the department, though not all are accused of sending racist texts. Cases involving serious crimes have already been disrupted by the revelations, including the dismissal of charges and a major payment from the county to help assess how big the problem is.

It was unclear whether the shooting tied up resources from other calls.

Antioch District 1 Councilmember Tamisha Torres-Walker, who herself lost her brother to gun violence nearly two decades ago, called the incident “tragic” but added she wanted to be careful what she said.

“I’m praying for the family, but I don’t want to make this political,” she said. “And what I will say is that I am still of the mind that police do not prevent crime in communities; however, response times for law enforcement and first responders could mean a matter of life and death for an individual impacted by violence.”

She added: “Young people should always be safe, and from what I understand, there was an attempt to make the party safe by doing pat downs, and trying to make sure that no violence that occurred, and I think that needs to be acknowledged.

Torres-Walker also said “the city needs to aggressively implement violence prevention and intervention strategies to get out ahead of this kind of violence.”

The city recently received a state grant from the California Prevention Intervention Act, with the goal of breaking the cycle of violence, by engaging people in neighborhoods and communities most impacted by gun violence and encouraging them to go down different paths. The program is in its infancy and has yet to be implemented, she said.

Messages left with Antioch police spokesperson Ashley Crandell were not returned Monday.

Thorpe said he repeated to the chief his position that the officers caught in the scandal should be fired. The state’s Department of Justice is investigating those allegations.

“The officers involved in the racist text-messaging scandal (who are currently on administrative leave) need to be fired immediately,” Thorpe said. “(Then) we can free up those positions and hire new police officers directly from the academy.”
