It didn't take authorities long to figure out who did it and track him down. Her husband was found dead at a home in Brookshire.
Valerie Robinson worked for Katy ISD for 18 years. According to investigators, she was shot by her estranged husband Gregory Robinson in the parking lot of Tompkins High School as she arrived for work. After that, he fled to their home in Brookshire.
After hours of watching the couple's home in Brookshire, law enforcement stormed in with guns drawn. Moments later they came back out, telling us they found a man dead inside. It appeared he shot himself in the head.
Family and friends prayed together after hearing the news. Authorities tell us Valerie Robinson was 46-years-old. She was shot and killed in the parking lot outside Tompkins High School near Katy where she worked at the cafeteria. It was a little after 6am Friday and school was not yet in session for the day.
"I'm still in shock," said Valerie's sister Audrey Ephram. "I don't know what could have driven him to do that."
Ephram says the couple had been married about 29 years and that they kept to themselves. But she does say her sister moved out of the couple's Brookshire home a few months ago.
"To know that you ain't gonna see her smiling face any more," Ephram said.
Brookshire is a small community of only about 4,000 -- a place where most everybody knows everybody. Something like this is disturbing to all.
Resident Kendra McKinney said, "It's sad. My heart is really heavy right now. I been knowing the people for a long time, you know."
Authorities aren't saying if they know what might have motivated the apparent murder/suicide.
Classes were held as scheduled at Tompkins HS on Friday. Some parents, however, did retrieve their children, telling us they just didn't feel safe having them on campus after the shooting.
