BROOKSHIRE, Texas -- The death of a Houston firefighter in a crash in Brookshire last week has been ruled a suicide.

Jason Hamilton, 43, a 12-year veteran with the Houston Fire Department, died on Jan. 27 in the crash that killed a woman, identified as Shelley McKay, on I-10.

Officials say Hamilton was driving a pickup truck that went over the median from an access road into the westbound I-10 mainlanes, colliding with an SUV.

The Houston Professional Firefighters Association released a statement Tuesday, saying:

“The troubling circumstances of Jason Hamilton’s death are a grim reminder of the prevalence of firefighter suicides and the terrible effects they have on families, friends and, in this case, innocent victims.

"Houston firefighters continue to grieve for the Hamilton and McKay families.

“Please continue to keep in your thoughts and prayers Jason’s wife, Lara, and their two sons, Cody and
Bruce. We ask the same for the family of Shelley McKay, especially Ms. McKay’s daughter, Megan
McKay, who was critically injured in the crash of the two vehicles."
