A Texas state trooper and married father of children has died five days after being shot in an ambush last week.

Texas Highway Patrol Trooper Chad Walker was ambushed on Friday evening while responding to what he apparently thought was a disabled vehicle parked on the side of a rural road just outside of Mexia, a small town about 40 miles northeast of Waco. Walker, who was alone, pulled up behind the vehicle and was shot in the head and abdomen before he could get out of his patrol car, according to a statement from Todd Snyder, regional director of the Texas Department of Public Safety.

"Our DPS family is absolutely heartbroken at the loss of one of our brothers in uniform who was killed in the line of duty," DPS Director Steven McCraw said in a statement announcing Walker's death. "Texas Highway Patrol Trooper Chad Walker was committed to protecting the people of Texas. His sacrifice will never be forgotten, and we ask that you keep his family, friends and colleagues in your prayers during the difficult days ahead."

Law enforcement officials had said on Tuesday that Walker "no longer display[ed] signs of valuable brain activity."

"After extensive life-saving efforts conducted by the Baylor Scott and White medical professionals, it has been determined that Trooper Chad Walker no longer displays signs of viable brain activity and he remains on life-support until he can share the gift of life as an organ donor," the Texas Department of Public Safety said in a statement Monday. "This final sacrifice embodies Trooper Walker's actions throughout his life and service as a Texas Highway Patrol Trooper. The Walker family is grateful for the continued support and prayers as they remain at Chad's side."

Snyder alleged the suspected gunman, identified as 36-year-old Dearthur Pinson of Palestine, Texas, saw the patrol car and "immediately emerged from the driver's seat of the disabled vehicle armed with a handgun and fired multiple rounds at Trooper Walker through the patrol unit's windshield." Pinson then allegedly walked back to his vehicle, retrieved a backpack and fled the scene on foot, Snyder said.

Walker, who had been a member of the Texas Department of Public Safety since 2015, was transported to a Waco hospital in critical condition. Counselors and a Texas Rangers chaplain have been with Walker's wife and their 15-year-old son, 7-year-old twin daughters and 2-month-old baby girl, according to Snyder.

Since the shooting, more than $200,000 has been donated to Walker's family via an online crowdfunding campaign to assist with the family's medical expenses.

On Saturday night, Pinson was found dead from an apparent self-inflicted gunshot wound in a house in Mexia, where he had barricaded himself during a standoff with authorities, according to a statement from the Texas Department of Public Safety.

The Texas Rangers are leading the investigation into the incident.

According to criminal records, Pinson had a history of run-ins with the law. In November 2007, he was sentenced to a maximum of 10 years in prison for armed robbery in Texas' Houston County.

Trooper Joseph Gallagher was hit by a vehicle in December 2017 when he stopped to help another driver who had broken down and passed from his injuries Friday, March 26, 2021.

Acting Superintendent Kevin P. Bruen announced Trooper Gallagher's line-of-duty death on Saturday.

Trooper Gallagher, who was 35 at the time of the crash, was hit on an overpass leading to the Long Island Expressway near Brentwood on December 18, 2017. 

State Police say Trooper Gallagher had stopped to help a motorist who had broken down. He was setting up emergency flares in the road when he was hit.  

Trooper Gallagher is originally from South Buffalo and later lived in West Seneca. He joined the State Police in 2014. 

He was most recently assigned to Troop L, which covers Nassau and Suffolk counties. He also worked in Troop T (Thruway) and Troop F.

After the crash in 2017, his uncle, William Gallagher, of Buffalo, posted on Facebook that his nephew was a rescue helicopter pilot for the Coast Guard in Detroit before he joined the State Police. 

Trooper Gallagher is survived by his wife, two children, parents, and siblings.

Trooper Gallagher died on the same date New York State Police suffered another loss 10 years ago. Trooper Kevin Dobson, of SP Clarence, was killed on March 26, 2011 while conducting a traffic stop on the 290 in Tonawanda.

Members of the State Police honored Trooper Dobson Friday with a special ceremony at the barracks in Clarence.

Gov. Andrew Cuomo on Saturday ordered flags on state government buildings to be flown at half-staff in his memory, starting Sunday.

"Trooper Gallagher is a hero to all New Yorkers — he dedicated his life to public service and worked to keep us safe," Governor Cuomo said in a statement.

"His tragic passing is a reminder of the selfless actions so many brave first responders take each day. We will never forget him, and to honor his memory, I am directing flags be flown at half-staff to honor his memory."

“It is with profound heartache and unfathomable sadness that I inform you of the death of Trooper Todd Hanneken. We are asking the public to respectfully give consideration to the family of Trooper Hanneken and the ISP while we grieve and work through this tragedy,” stated Director Brendan Kelly.

Ohio State Highway Patrol Trooper Hiram Morales and Cleveland Division of Police Officers Molly Madaras and Cory Rose were honored Tuesday for their heroic actions during a January house fire.

Trooper Morales was given the Superintendent's Citation of Merit. Officers Madaras and Rose were presented with a Certificate of Recognition at the Patrol's Cleveland District Headquarters.

On Jan. 23, 2021, a resident told Trooper Morales that there was a house fire in the 3700 block of W. 47th St. in Cleveland. Residents also told the trooper that there was a man in a wheelchair who lived in the house next to the burning home.

The fire was spreading rapidly, so Trooper Morales entered the home. That's when he saw an elderly woman trying to help and elderly man, whose wheelchair had gotten stuck in the doorway. Trooper Morales was able to guide the couple outside, giving them instructions in Spanish because they were not proficient in English.

As that was happening, Cleveland Officers Madaras and Rose also arrived on scene, and assisted in getting the couple out of the home and to safety.
