Robbery suspect, SAPD officers involved in fatal shooting Monday identified

‘He should have been in jail,’ Police Chief William McManus said on Monday

SAN ANTONIOUpdated Sept. 6:

The San Antonio Police Department identified the two officers involved in the shooting as Officer Juan Dominguez, who has been with SAPD for 12 years. The other officer is Officer Matthew Raster, who has 10 years of service with the law enforcement agency.


The San Antonio Police Department has identified the 27-year-old suspect officers shot and killed during a pursuit on Monday.

The man was identified by police as Jacob String. The Bexar County District Attorney’s Office said he had been out on parole after being released from prison in May for an offense of evading arrest with a vehicle.

The shooting happened on the Southeast Side near Southcross and Prestwick, where officers began to pursue String following two robberies earlier Monday.

During the pursuit, McManus said String may have fired at police with a weapon, prompting officers to fire back, killing him.

SAPD said Tuesday that further investigation revealed String had drawn a gun from his waistband and pointed it toward officers. However, he did not fire any rounds.

McManus said the suspect had been wanted on multiple aggravated robbery warrants.

The Bexar County District Attorney responded to criticism following the police shooting.

DA Joe Gonzales responded to McManus’ comment that the suspect “should have been in jail.” He issued the following statement:

“The Texas Constitution gives all Texans charged with a crime a constitutional right to bail except under limited circumstances.

“Hard evidence is required to convict a person of a crime. Evidence is gathered either at a crime scene or through subsequent investigation by a law enforcement agency. Witnesses are interviewed, statements taken, and photos taken. Documentation of the crime and crime scene are crucial to a successful prosecution and conviction.

“Several cases in this offender’s criminal history were dismissed because no such evidence was provided to the District Attorney’s office by SAPD. This office, which has an obligation to seek justice, cannot prosecute cases against defendants for which there is insufficient evidence.

“Prior to the dismissal of these cases, the lack of evidence was specifically brought to the attention of the San Antonio Police Department. In fact, this office requested that it be provided with the results of the investigation and the evidence required to prosecute on several occasions. Our prosecutors proactively engaged with SAPD in an attempt to remedy the incomplete filings.

“The individual involved in last night’s shooting was on parole, not bond, at the time of the shooting. Our office prosecuted him and obtained a prison sentence for the offense of evading arrest with a vehicle on November 30, 2022. He was released from the Texas Department of Corrections on May 15, 2023. The decision to release him from prison was made by the Texas Board of Pardons and Paroles.

“Prior to last night, the offender did have a previous criminal history – but not a criminal history sufficient to hold him without bond.

“We prioritize public safety and the safety of all our first responders. Our office is committed to pursuing justice – but we cannot proceed without evidence. In fact, prosecuting a defendant without having evidence is not only a violation of our oath, but it also potentially subjects to the city, county, and the individual law enforcement personnel to liability for wrongful prosecution.”

McManus has expressed frustration with the DA’s Office recently after five shootings involving his officers in 12 days. In those incidents, six officers were wounded and three suspects, some of whom he called “violent offenders” wanted on warrants, were shot.
