SAN ANTONIO, Nov 21 (Reuters) – A suspect was arrested on Monday in the fatal ambush shooting of a San Antonio police officer, local television reported, one of four officers shot in the line of duty in Texas, Missouri and Florida on the same day.
The attacks on Sunday, which injured three other officers and led to the shooting death of a suspect, revived painful memories of deadly ambushes targeting police in July in Dallas and Baton Rouge.
KENS TV in San Antonio, citing multiple sources, said a suspect was arrested for the killing of 50-year-old Benjamin Marconi, a 20-year veteran of the San Antonio force who was fatally shot as he sat in his squad car during a routine traffic stop outside the city's police headquarters.
San Antonio Police planned a news briefing.
The assailant stopped his car behind the police cruiser, walked up and shot the officer in the head through the window as he was writing a ticket, San Antonio Police Chief William McManus told a news conference earlier on Monday.
The gunman then reached through the window, fired a second shot into the officer, returned to his vehicle and sped away.
A total of 57 U.S. law enforcement officers have been killed by gunfire so far this year, a 68 percent increase from the same period in 2015.
Also on Sunday, a 46-year-old St. Louis police sergeant was shot in the face by a person in a car who pulled up beside the officer's cruiser at an intersection then fled. St. Louis Police Chief Sam Dotson said the wounded officer was conscious and able to speak after the attack.
The suspect was later killed in a shootout after officers spotted his car, police said on Monday.
Meanwhile, a third police officer was shot on Sunday during a traffic stop on Sanibel Island on Florida's Gulf Coast but was not seriously hurt, local media reported.
The officer was treated for a shoulder wound, according to the reports, while the suspect was apprehended at his home on an island off Fort Myers.
'WORST NIGHTMARE'
In a fourth incident, a police officer in Kansas City, Missouri, was shot and wounded during a struggle with an armed suspect who tried to flee after a traffic stop, police said.
The suspect was killed and a Kansas City police spokeswoman said investigators were determining whether the officer was shot accidentally by one his colleagues.
In Texas, federal, state and local authorities had joined the search for the San Antonio gunman, whom McManus described as "extremely dangerous, both to the police and to the public."
About four hours before the shooting, he said, surveillance video showed the suspect had briefly entered police headquarters and asked a question of a desk clerk before leaving.
McManus said it was not immediately known why the suspect entered the building, and he declined to say what the clerk was asked.
Investigators did not have any immediate clues to the man's identity, he said. They found no apparent link with the man whom the officer pulled over in the traffic stop.
"This is everyone's worst nightmare," McManus said. Referring to the recent ambush killings of police officers in Texas and Louisiana, he said, "Unfortunately, like Dallas, like Baton Rouge, it's happened here now."
The latest shootings come amid an intense national debate over the role of law enforcement and especially the use of force by officers against minorities.
