Man arrested after Texas police officer shot dead while writing traffic ticket

A man has been arrested after a police officer was shot dead while sitting in his car writing a traffic ticket in Texas.

San Antonio Police Chief William McManus confirmed 31-year-old Otis Tyrone McKane, had been arrested on a capital murder warrant without incident after the car he was driving was stopped on an interstate highway.

Detective Benjamin Marconi, 50, was shot dead on Sunday outside police headquarters in San Antonio.

Surveillance video shows the suspect there about four hours before Det Marconi was shot.

The suspect asked a desk clerk a question but left before receiving an answer, said Mr McManus, who declined to say what the man asked.

Mr McManus had previously said he did not believe the suspect had any relationship to the motorist who was pulled over initially.

Also on Sunday a police officer was shot twice in the face in St Louis, Missouri, while he sat in traffic in a marked police car.

The suspect in the Missouri shooting, George P Bush III, was later killed in a shoot-out with police.

Bush was wanted for questioning over recent violent crimes that included several robberies, a carjacking and perhaps a killing, St Louis Police Chief Sam Dotson said.

At least two other police officers were wounded in shootings in other cities in the US on Sunday.

A police office in Gladstone, Missouri, was injured after being shot when he pulled over a car. The suspect was shot and killed.

While in Sanibel, Florida, officer Jarred Ciccone was shot in the shoulder during a traffic stop.

Both officers are recovering.

Police arrested Jon Webster Hay, 49, about 90 minutes after the shooting in Florida. They said he was booked into jail on an attempted murder charge after he was released from hospital, where he was treated after being wounded during a stand-off and shoot-out with officers.
