Police have identified Shane M. James of San Antonio as the shooter. It's the 50th mass killing event in Texas in the last 15 years, according to the AP/USA TODAY/Northeastern University mass killings database. Mass killings are defined as the intentional murder of four or more victims, excluding the perpetrator.

Here's what we know about the shootings' timeline, as told by interim Austin Police Chief Robin Henderson on Tuesday evening and by Bexar County Sheriff Javier Salazar at a news conference Wednesday afternoon.

10 p.m. Monday to 9 a.m. Tuesday: James' parents shot, killed in San Antonio family home

At a news conference Wednesday, Salazar said police believe the first shooting in James' rampage occurred in his family home in San Antonio, where James is believed to have killed his mother Phyllis James, 55, his father Shane M. James, Sr., 56.

Police believe the double homicide occured between 10 p.m. Monday night, when a sibling of the suspect last spoke to one of the victims, and 9 a.m. Tuesday morning, but are seeking tips from the public to narrow that window.

The bodies were not discovered until after 7:45 p.m. Tuesday night, when the San Antonio sheriff's office received a call from Austin police asking for help investigating the suspect's home in the 6000 block of Port Royal Street.

Anyone with information is asked to call 210-333-5600 or email bcsotips@bexar.org.

On Tuesday evening, police received calls reporting a burglary in progress at a home in the 5300 block of Austral Loop in South Austin.

Police later found two shooting victims inside the house.

Ten minutes after police got the call about the burglary, officers were chasing the suspect, who was fleeing in a vehicle, while EMS attended to the officer who had been shot and was taken to a hospital at 7:04 p.m.

During that time, officers checked on the home on Austral Loop and found two bodies inside, Henderson said. They were pronounced dead on the scene.

One of the victims was a mother, who was shot while on a walk with her 1-year-old toddler, her family members told the American-Statesman.

While being chased by police, James crashed the vehicle at the intersection of Texas 45 and FM 1826, Henderson said. The shooter's rampage in Austin had gone on for more than eight hours.

It was not until after the suspect was arrested that police were able to connect multiple events to James, Henderson said.
