San Antonio police are investigating the motive of a man accused of opening fire on his co-workers at a landscaping business Saturday morning, killing three people before he died of a self-inflicted gunshot wound.

A total of five people were killed and two injured in shootings on Saturday, including the suspect in the landscaping business shooting, according to police reports.

Here’s what San Antonio authorities investigated over the weekend:

After an hours-long manhunt Saturday morning, police found a suspect in a fatal triple shooting on the Northeast Side dead of a self-inflicted gunshot wound.

Police said Jose Hernandez Galo, 21, went to a landscaping supply business in the 4400 block of Stahl Road around 7:30 a.m. and allegedly started shooting at the employees, striking three who later died of their injuries.

The victims were a 24-year-old woman and two men, ages 38 and 48, according to police. The victims and Hernandez Galo were employees of the landscaping business, a preliminary police report says.

Officers were able to secure the location Saturday morning and launched a search for a suspect based on witnesses’ description.

SAPD’s SWAT and negotiators arrived at the scene around 9:45 a.m., with the Texas Department of Public Safety also present. A drone was used to locate the gunman, while local residents were advised to stay indoors.

Around 11:40 a.m., Chief William McManus posted on social media that Hernandez Galo was found with a self-inflicted gunshot wound. The Bexar County Medical Examiner said he died of a gunshot wound to the head and ruled his death a suicide.

A motive for the shooting was still unclear Sunday, police said. At the scene Saturday morning, Chief William McManus said the shooting was “not random.”

Around 1:45 a.m. Saturday, police responded to a shooting in progress in the 400 block of Avondale Ave. in the city’s Southeast Side. There, they found a 53-year-old man with a gunshot wound.

According to a preliminary police report, the man’s girlfriend told police she had shot him. Police said the woman, 61, has been charged with aggravated assault with a deadly weapon.

The man was taken to a hospital with life-threatening injuries. Police said they do not know what led to the shooting.

A few hours later, around 4:30 a.m., police were called to the 5000 block of Culebra Road in the city’s near Northwest Side, following reports of shots fired.

When they arrived, officers found a man lying on the ground with an apparent gunshot would, according to a preliminary police report. He was pronounced dead at the scene.

Witnesses told police they saw a man dressed in all-black clothing running away from the area. Police on Saturday had not identified the victim nor the suspected shooter.

At about 11 p.m. Saturday, officers responded to another shooting in the 5900 block of Spring Buck. When they arrived, they found a 33-year-old man with a gunshot wound to his leg. He was taken to the hospital with injuries that were not life-threatening.

A 37-year-old man at the scene told police that they had been arguing before the shooting. When the 37-year-old man tried to walk away, the 33-year-old man attacked him.

The 37-year-old was “in fear for his life and shot the suspect in order to stop the physical assault,” according to a preliminary police report. He suffered minor injuries during the altercation.

A man was riding a bike around 10 p.m., headed southbound in the 2500 block of Fredericksburg Road, when he encountered a bus traveling in the same direction, according to a preliminary San Antonio police report.

The bus “allegedly side-swept the complainant on his bicycle, causing him to fall off,” the report says. The bus driver did not stop to check on the cyclist.

The injured bicyclist was taken to the hospital. The VIA bus driver has not been identified.
