Timeline: How the shooting at a Texas elementary school unfolded
The suspected gunman bought the AR-15-style rifle two days after he turned 18.
What began as a milestone marking adulthood ended in tragedy after a suspected gunman used the AR-15 style rifle he purchased days after he turned 18, authorities said.
Uvalde High School student Salvador Ramos allegedly purchased two assault rifles just days after turning 18 and used them to carry out one of the worst school shootings in U.S. history -- all within a span of eight days, authorities said.
Ramos was known for fighting and threatening fellow students, some classmates told ABC News. He allegedly exhibited unusual behavior such as threatening classmates and claiming to have cut scars into his face, classmates said.
Twenty-one people, including 19 third and fourth grade children, were killed in the attack, law enforcement officials said. Two teachers were among those killed. Another 17 people were wounded, including three law enforcement officers.
This is how the shooting unfolded:
Salvador Ramos asks his sister to purchase him a gun, according to Steve McCraw, director of the Texas Department of Public Safety. She flatly refuses.

In a four-person group chat on Instagram, Ramos discusses being a school shooter, according to McCraw.
In a four-person group chat on Instagram, Ramos discusses buying a gun, according to McCraw.
In a four-person group chat on Instagram, according to McCraw, a user says to Ramos, "word on the street is you're buying a gun." Ramos replies, "Just bought something. RN."
Ramos posts on Instagram, "10 more days." A user replies, "are you going to shoot up a school or something?" Ramos responds, "No. And stop asking dumb questions. You'll see."
Ramos moves in with his 66-year-old grandmother, Celia, according to McCraw, from a press conference Wednesday afternoon.
Around May 9
Ramos meets "Cece," the recipient of several messages Ramos sent on the day of the shooting, on the social media app Yubo, she told ABC News.
The teen, who lives in Germany, said she and Ramos would "join each other's live" streams on Yubo.
Cece alleged that there were other warning signs in hindsight, including that Ramos would ask others on Yubo "if they would want to be famous on the news."
Ramos turns 18, according to the Bureau of Alcohol, Tobacco, Firearms and Explosives and multiple law enforcement sources.
Ramos buys a semi-automatic rifle at a local sporting goods store called Oasis Outback, McCraw said.
Ramos purchases 375 rounds of ammunition for that rifle, McCraw said. It is not known where he purchased that ammunition.

Ramos buys a second semi-automatic rifle at the same store, McCraw said.
Tuesday, May 24
Morning: An Instagram account that law enforcement sources tell ABC News they believe is connected to Ramos sent another user on the social media platform a photo of a gun lying on a bed, according to a user who shared direct messages from the suspect's alleged account with ABC News.
11 a.m.: Ramos allegedly had three one-on-one direct communications on Facebook with Cece. The first message said he was going to shoot his grandmother, Texas Gov. Greg Abbott said in a press conference.
Another one-on-one message said he had shot his grandmother, and the third said he was going to shoot an elementary school, but did not specify the school, Abbott said.
It is not believed Cece saw the messages until after the shooting occurred.
Shortly after 11 a.m.: Ramos shot his 66-year-old grandmother in the head at their residence, according to McCraw. He flees. She was able to run across the street and call police, McCraw said. She was taken to the hospital via helicopter. She has survived.
11:27 a.m.: A Robb Elementary School teacher exits the school's west-facing entrance door to transport food from her parked car to the classroom, The Associated Press reported and the Texas Department of Public Safety confirmed to ABC News on Tuesday. The teacher witnesses the car wreck and runs inside to retrieve her phone, using a rock to keep the door propped open.
11:28 a.m.: Ramos crashes his vehicle into a ravine adjacent to Robb Elementary School, according to McCraw. He emerges from the passenger side of the vehicle wielding a Daniel Defense AR-15-style assault rifle. Ramos wore a backpack containing ammunition and tactical gear, including a vest that could hold ammunition, sources said, but there was no armor or fabric that would protect him from gunfire.
After exiting the vehicle, Ramos fires four shots at two witnesses outside a nearby funeral home, neither of whom was struck, and then makes his way toward the school, surveillance video released earlier this month shows.
11:29 a.m.: The Robb Elementary teacher calls 911 to report the car crash. While on the phone with police, she returns to the propped-open door and sees Ramos approaching the school with a gun, which she tells the dispatcher. The teacher then removes the rock she had used to prop open the door and shuts the door -- but the door does not lock, the AP reported and Texas DPS confirmed to ABC News.
McCraw said initially that the teacher left the door propped open. But the Texas DPS corrected itself days later, telling ABC News that investigators have now determined that the teacher closed the door. McCraw said in testimony to the Texas Senate on June 21 that the locking mechanism was not engaged, though the teacher could not have known that from inside the building.

In doing so, the officer drove past the suspect who was hiding behind parked cars, McCraw said.
11:32 a.m.: The gunman fires multiple rounds at the exterior of the school, including some that went through a window, according to McCraw.
