COLLEGE STATION, Texas -- Relatives of a driver killed on a rural Texas highway when another car swerved into his lane, killing a college professor in that vehicle, said Monday that the man was headed to surprise his mom for Mother’s Day.

Jan Bigbee Weesner said she didn’t even know her son, 28-year-old Evan Bigbee, was making the trip from Weatherford to Brenham until a state trooper arrived at her home Saturday.

“They’ve always loved to surprise me,” Weesner said of her two sons in an interview with the Bryan-College Station Eagle. The other son was home at the time.

Also killed in the accident on Texas Highway 90 was Prairie View A&M professor Eulalio G. Garza III. He was a passenger in the car that authorities say swerved into Bigbee’s lane due to “driver inattention.”

Garza died after attending the university’s spring graduation service earlier that day. The driver of his car was taken to a Houston hospital and remained in serious condition, the newspaper reported.

The accident happened near Bedias, about 60 miles north from Bigbee’s mother’s home in Brenham.
