The latest in the case of a Texas teenager serving probation for killing four people in a drunken-driving wreck after invoking an "affluenza" defense (all times local):

6:45 a.m.

Police say the mother of a fugitive Texas teen known for using an "affluenza" defense in a fatal drunken-driving accident is being held in a Los Angeles jail after being deported from Mexico.

Officer Norma Eisenman says Tonya Couch was picked up by the LAPD's fugitive task force shortly after 1:30 a.m. Thursday at Los Angeles International Airport.

Eisenman says Couch will be held until U.S. marshals arrive to take her to Texas, where she and her son, 18-year-old Ethan Couch, live and where he was on probation for the 2013 crash.

Authorities believe the Couches fled to Mexico in November as prosecutors investigated whether he had violated his probation. Ethan Couch remains in a Mexican jail.

Eisenman didn't know why Tonya Couch came through Los Angeles or when she would be transported.

Deputy U.S. Marshal Eugene Hwang said Thursday that he couldn't immediately comment.
