More than 600 shots were fired by 33 Stockton police officers at the getaway car used by a trio of bank robbers, who took three women hostage and entered into a ferocious rolling gun battle with cops last year, according to a comprehensive report on the incident released Monday.

The report came as the husband of Misty Holt-Singh, one of the hostages killed by police gunfire, planned to file a civil lawsuit Tuesday against the city of Stockton, saying police used excessive force in their response.

The July 16, 2014, episode, in which two of the three suspects were killed by police gunfire after the botched robbery at a Bank of the West branch, was one of the most violent and chaotic clashes between cops and criminals in law enforcement history, authors of the report wrote.

The rampage that saw the suspects fleeing at over 100 mph in a hostage’s Ford Explorer while recklessly spraying gunfire from an AK-47 assault rifle was complicated by a bankrupt city’s cash-strapped police force staffed by rookie officers with limited equipment and resources, the report found.

The Police Foundation, an organization that provides independent reviews of police incidents, on Monday published “A Heist Gone Bad,” a comprehensive 60-page report on the incident and the police response.

“The goal of this review is to provide lessons learned that can then be applied in the field, increasing the safety of both law enforcement personnel and civilians,” wrote retired Jim Bueermann, president of the Police Foundation.

Bueermann, a retired police chief of Redlands (San Bernardino County), said the report was not intended to “criticize or blame the men and women of the Stockton Police Department.”

Among the findings was that after the suspects’ vehicle was disabled, dozens of officers fanned out and many opened fire.

“There were no dedicated shooters,” the report found. “There was very little control, just police officers trying to stop a threat. The gunfire roared as more than 600 shots were fired.”

Two hostages had escaped after one jumped from the fast-moving vehicle, and another was forced out after one of the suspects accidentally shot her. But in then end, the third hostage, 41-year-old Misty Holt-Singh, lay dead from 10 wounds, all from police gunfire, the report says.

Officers said a surviving suspect, 20-year-old Jaime Ramos, likely used Holt-Singh as a human shield in the backseat of the SUV.

In the front seat, Gilbert Renteria Jr., 30, and Alex Martinez, 27, both documented Norteño gang members from Stockton, were shot dead. Prosecutors have sought the death penalty for Ramos.

Paul Singh, Holt-Singh’s husband, planned to announce a lawsuit against the city of Stockton on Tuesday after filing a legal claim, a precursor to a civil suit, earlier this year.

“The information discovered about the tragedy of that day only confirms that city of Stockton police officers violated numerous standard police protocols in their response,” the family’s attorney, Gregory Bentley, said in a January statement.

Among the report’s findings were that 100 veteran officers had left the department in the wake of the city’s bankruptcy, leaving mostly officers with limited training on the force.

What’s more, the department, due to cutbacks, had no air support of its own to assist in the chase, the report states.

“One of the frustrations we repeatedly heard during our interview with Stockton police officers was they were dealing with an event that they had never trained for, let alone truly considered,” Bueermann wrote.

In the end, the suspects fired over 200 rounds, disabling 14 police vehicles during the hourlong pursuit in what Bueermanna described as a “law enforcement nightmare.”
