BURLESON, Texas — A 13-year-old boy says he's still trying to make sense of a deadly wreck caused by a 16-year-old drunken driver whose defense infamously argued he suffered from "affluenza."

Lucas McConnell spoke briefly Wednesday at a news conference organized by his family's attorney, who announced that he'll pursue a civil trial of Ethan Couch's family.

Couch was given probation last year after admitting to killing four people on a dark, remote North Texas road while driving a pickup truck drunk and with drugs in his system.

The McConnell family's attorney, Todd Clement, said he intends to take the testimony of Couch and his parents, Fred and Tonya.

While Clement didn't rule out a settlement, he said he wanted a trial for "accountability and responsibility."
