A teenage boy opened fire with his father's shotgun and handgun at Santa Fe High School a few miles down the road, in an attack that left 10 dead, eight of them children, in the first mass school shooting amid the Parkland students' movement.
The former student who is charged with killing 17 students and faculty members at Marjory Stoneman Douglas High School in February 2018, was allegedly abusive to an ex-girlfriend and fought her new boyfriend ahead of the shooting - even threatening to kill him.
There's still no official word when students will return to school, but the district has canceled classes Monday and Tuesday.
Among them was 18-year-old Santa Fe senior Monica Bracknell, a shooting survivor who hugged Mr. Abbott outside the Arcadia First Baptist Church and urged him not to use the tragedy as fodder in the gun-control fight.
On Sunday, the first of the funerals took place.
Since the shooting, Houston Police Chief Art Acevedo and Mayor Sylvester Turner have repeatedly called for new gun control legislation, which could include universal background checks for gun buyers, bans on bump stocks and high-capacity magazines and money for metal detectors in schools.

According to an affidavit filed in court, he waived his right to remain silent and admitted "to shooting multiple people".
Many of those student activists have taken aim at the pro-gun National Rifle Association.
