ANNA, TEXAS -- We're learning more about a fatal accident that happened at 121 and FM 455 in Anna two weeks ago.
Last week, Anna police mapped the accident in an attempt to get a better idea of what happened.
Sgt. Jeff Caponera says police now believe Plano firefighter Lindy Lawley was driving north in the southbound lane when he crashed into Zelia Alvarez head-on in the southbound lane.
Police aren't sure whether Lawley veered into her lane or was trying to pass.
Lawley remains in the hospital in critical condition.
Alvarez died in the collision.
