A Texas high school baseball player and his parents have died after they were struck by an 18-wheeler while heading to a game. The Rogers Independent School District announced the deaths of high school junior Connor McCaffety and his parents, Meghan and Clint, in a Facebook post on Tuesday, April 1. “It is with overwhelming sadness that I share the tragic loss of Connor McCaffety, a junior at Rogers ISD,” Superintendent Duana Brashear wrote. “[On Monday,] March 31st, Connor and his family were involved in a devastating accident on HWY 36 in Milano. Connor, his mother Meghan, and father, Clint did not survive the accident. Our hearts go out to everyone that is grieving this loss.” The family was leaving Connor’s high school golf tournament in Brenham and on their way to a baseball game in Rogers on Monday evening, Brashear told CBS affiliate KWTX. Texas Department of Safety Sgt. Bryan Washko said that at the time, several vehicles halted at a flagman in a construction zone. "There the vehicles were completely stopped,” Washko told CBS affiliate KBTX, “and for reasons unknown at this time, an 18-wheeler failed to control their speed and collided with multiple vehicles, and unfortunately there are three lives that were tragically taken.” The crash is reportedly under investigation. PEOPLE reached out to the Texas DPS for additional information on Thursday, April 3. The family is survived by a 14-year-old daughter who was not in the car at the time of the crash, KBTX reported. Brashear wrote in the Rogers ISD Facebook post that support for students and staff will continue in the coming days and weeks following the tragedy, adding that counselors will be available on site at all campuses. “Please keep this family in your prayers. Love each other,” Brashear’s statement added. Connor's GPS Legends Baseball mourned the family in a Facebook post. “It is with extremely heavy hearts that we mourn the passing of beloved GPS family members Connor, Clint & Meghan McCaffety,” the team said. “A truly incredible family gone way too soon. Please keep younger sister Kelsey in your prayers. Hold your loved ones tight.” In an interview with KWTX, GPS Legends Baseball founder Brandon Puffer described Connor as a "fierce competitor."
