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):

1 a.m.

The mother of a fugitive 18-year-old known for using an "affluenza" defense in a drunken-driving case is expected to appear in a Los Angeles courtroom.

Tonya Couch is expected to appear for an extradition hearing in downtown Los Angeles on Tuesday. Prosecutors are planning to ask that she be extradited to Texas.

The 38-year-old Couch was deported from Mexico and was flown to Los Angeles early Thursday morning.

Her attorneys say in a statement that Couch looks forward to returning to Texas as soon as possible to have her day in court.

The statement says that while the public may not like or agree with what Couch did, she never violated Texas law when she and her son went to Mexico.

Tarrant County Sheriff Dee Anderson has said he believes Couch and his mother fled to Mexico in late November after a video surfaced that appears to show Couch at a party where people were drinking, which would be a violation of his probation.

Her son, Ethan, is being held in an immigration facility in Mexico City.
