MANSFIELD (CBSDFW.COM) -- For the second time in two weeks, Mansfield Timberview High School is dealing with the sudden death of a community member.

On Saturday night, student Carlos Marquez was killed and three of his classmates were injured in a car wreck.

Just last week, Timberview coach Cody McCarty died at the age of 29.  It's thought that he suffered a heart attack.

The crash that killed Marquez happened at 11:30 p.m. on State Highway 360, just north of the school.

Marquez, who was 15, was riding in the back seat of the car at the time.  Police say the 17-year-old driver was trying to pass a slower car when she lost control, veered into the median, and hit a tree.

Timberview brought in several grief counselors Monday to help the students and staff deal with Marquez' death.
