According to Sadie Rodriguez, the mother of 16-year-old school shooting victim Shana Fisher, her daughter was killed because she rejected the advances of shooter Dimitrios Pagourtzis for four months, culminating in a final rejection in front of their class.

Rodriguez told the Los Angeles Times, “A week later (Pagourtzis) opens fire on everyone he didn’t like, Shana being the first one.” In March’s school shooting in Maryland, the shooter used his father’s gun to shoot a student who recently ended a relationship with him in a similar display of toxic masculinity. Police say that Pagourtzis confessed to the killings of ten people, but offered no motive yet.

Texas governor Greg Abbott told reporters that Pagourtzis got the guns from his father who had more than likely gotten them through legal means. Houston police chief Art Acevedo spoke posted on Facebook Friday to elaborate on his evolving feelings about gun control, writing, “The hatred being spewed in our country and the new norms we, so-called people of faith are accepting, is as much to blame for so much of the violence in our once pragmatic Nation. This isn’t a time for prayers, and study and Inaction, it’s a time of prayers, action and the asking of God’s forgiveness for our inaction (especially the elected officials that ran to the cameras today, acted in a solemn manner, called for prayers, and will once again do absolutely nothing.)”

Notably, unlike the Parkland shooting, this one has not sparked or drawn much debate regarding gun control or school safety, despite it occurring on a school campus which had officers in place trained for school shooting situations. Students and parents haven’t had the same momentum in organizing around gun control after this shooting, which marks the ideological differences between Parkland, Florida and Galveston County, Texas, despite both cities being located in the South.
