The children's father, Stephen M. Brady, 32, who was driving, remained in serious condition yesterday at Maryland Shock Trauma Center.
Lentz was released yesterday from Shock Trauma.
State police sought yesterday to clarify their actions during another collision that Lentz had less than two hours earlier. In the earlier crash, he allegedly drove across the center line of a highway in Joppa in his work van and sideswiped another van occupied by a woman and seven children.
He allegedly continued driving, but his vehicle stopped running a half-mile away. He was issued several traffic citations but was not arrested. Within 90 minutes, Lentz, driving his own vehicle, was involved in the second accident.
Elena Russo, a state police spokeswoman, said that troopers who stopped Lentz after the first accident saw no indication that he was under the influence of alcohol, signs such as bloodshot eyes, erratic behavior or breath smelling of liquor. She also said that troopers don't generally do a full check of a driver's record in such cases. They usually only look to see whether the driver is wanted for arrest, she said. Lentz was not wanted at the time, but he had a history of driving offenses.
