Authorities say the accident Sunday afternoon happened when a Volkswagen Beetle slammed head-on into a dump truck. All four people in the subcompact car were killed on impact in the crash about five miles north of Midland.
The Texas Department of Public Safety identified them as driver Deborah Beck of Andrews and her three grandchildren - 8-year-old Tiffany Klein, 3-year-old Jeremyah Rodriguez and 2-year-old Sebastian Savage.
Trooper John Barton says dump truck driver 56-year-old Edwin Timmer also was killed, apparently in the ensuing fire. Barton says Timmer was talking with his wife after the crash but was unable to escape the truck, which was towing a trailer.
Barton says all five were wearing their seat restraints.
