AUSTIN, Texas (AP) — Texas authorities on Wednesday charged a man with capital murder following a wave of daylong violence across two major cities that left six people dead and two police officers recovering from gunshots, including one who was shot in the leg outside a high school in Austin.

A cyclist in Austin was also shot and wounded in a trail of attacks that began Tuesday morning and ended with the suspect crashing his car that evening during a police pursuit, Austin interim Police Chief Robin Henderson said. In all, four who died were found in two homes in Austin and two others were found in a home more than 80 miles (129 kilometers) away in the San Antonio area.

She did not immediately identify the suspect and said it was unclear what, if any, relationship the man had to the victims.

“We strongly believe one suspect is responsible for all of the incidents,” Henderson said during a news conference early Wednesday.

She said authorities did not determine the Austin attacks were connected until the final one at a home, which happened more than eight hours after a school police office was shot and wounded in a high school parking lot on the other side of the city.

In San Antonio, Bexar County Sheriff Javier Salazar said the bodies of two people were found inside a residence after deputies saw water coming out of the home, as though something was leaking inside. He said the deaths appeared to have occurred before the shootings in Austin.

“This occurred, and then the suspect drove to Austin and did what he did there,” Salazar told reporters.

The Travis County District Attorney’s Office said the suspect had been charged with multiple counts of capital murder but did not immediately release his name. Authorities said the man was in his 30s.

“Our hearts break for the shooting victims, injured officers, their families, and our communities impacted by yesterday’s senseless and tragic gun violence,” the office said in a statement.

The attacks were the country’s 42nd mass killings this year, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.

A timeline provided by Texas authorities revealed the wide ground the suspect allegedly covered between the attacks.

Henderson said it began with the Austin school district police officer being shot in the leg about 10:45 a.m. Tuesday outside Northeast Early College High School. Then, around noon, police who responded to a home after getting calls about gunshots found two people with signs of trauma. Police say one was dead and the other died at a hospital.

Another shooting happened shortly before 5 p.m., when a male cyclist suffered non-life-threatening injuries. About two hours later, police responded to a call of a burglary in progress at another home and found two people dead there. Henderson did not say how the four people in Austin died.

Henderson said that during the call at the last residence, an Austin police officer saw a man in the backyard. The man shot and wounded the officer who returned fire and was taken to a hospital, where he was listed in stable condition.

Police said the suspect, who was not hit, drove away and police chased him. He crashed at about 7:15 p.m. at a highway intersection and was taken into custody. The man had a gun, Henderson said.

She said the officer who was shot and the other officers were wearing body cameras and the video would be released within 10 business days.
