HOUSTON, Texas (KTRK) -- Tuesday's shooting of a Harris County sheriff's deputy was the latest in a disturbing trend of violence involving law enforcement officers from the Houston area over the past six months.

A review of records kept by ABC13 shows at least a dozen incidents, including four where law enforcement officers were killed since May 2020.
Separate incidents in 2021 included three deputies who were wounded outside a Midtown nightclub on Jan. 3, and two other law enforcement officers who were fired upon during chases.
The new year of violence began with the shooting outside Club Set in the 2900 block of Travis Street when those uniformed Harris County deputies were working extra jobs. Investigators said 25-year-old Joseph Anthony Gonzalez confronted the deputies with a gun during a fight in the parking lot and shot all three of them. One of the deputies returned fire and hit Gonzalez, the sheriff's office said. During the confrontation, Gonzalez's mother was shot in the leg and later died at the hospital. The investigation into whose gunfire hit her was still ongoing at last check.
A Houston police officer was shot at on Jan. 11 in the southeast part of the city and returned fire, hitting the shooter. The officer wasn't hurt and the suspect was seriously injured.
Two days later, a Harris County Precinct 6 deputy constable escaped injury as a chase suspect shot at him up to eight times in southeast Houston. The suspect ended up crashing into the back of a truck near the Gulf Freeway and was taken to a hospital with injuries. Authorities said at the time they believed the shooter was under the influence of drugs.
Deadly 3-week span for Houston police officers
Last year, two Houston officers were shot to death in a three-week span. Sgt. Sean Rios and Officer Harold Preston were fatally wounded during gun battles with suspects. Rios, a 25-year veteran of the department, was killed on Nov. 9. Preston was shot to death on Oct. 20 during a domestic violence call. Another officer was shot in the arm during the gunfight.
A rash of intentionally set fires in a Heights-area neighborhood prompted Houston Fire Department arson investigators to converge on the area in October, including Lemuel "DJ" Bruce. Bruce was shot and killed while tailing a suspect. According to ABC13 sources, Bruce and five other investigators were in the Timbergrove area, but they weren't looking for a suspect in particular and none of them was expecting to make a traffic stop in the neighborhood. The suspect was found nearby dead of a self-inflicted gunshot wound.
Earlier in the year, a Harris County deputy was fired upon while working an off-duty security job in October at a west Houston apartment complex, and officers were shot at in a Montrose-area neighborhood in a separate incident. The armed suspect was shot to death in that incident.
In May, a Fort Bend County Precinct 4 deputy constable was accidentally shot to death in what authorities called a friendly fire incident during a call about a suspicious person in the Sienna area. Deputy Caleb Rule was wearing a bullet-proof vest and was shot in the chest. He later died at Memorial Hermann Hospital. Rule served the constable's office for nine months and had worked for 14 years for the Missouri City Police Department.
As he asked for prayers Tuesday for Deputy Barragan, former Houston Police Officers' Union president Joe Grimaldi pointed to the trends while using the hashtag #EnoughIsEnough.
"We continue to be shot and assaulted at alarming rates," Grimaldi tweeted.
