The mother of a Texas teenager, derided for his "affluenza" defense for killing four people while driving drunk, posted bond on Monday and is set to be released from a county jail on Tuesday, the Tarrant County sheriff said.

Tonya Couch, 48, had her bail reduced on Monday to $75,000 from $1 million after her lawyers argued the original amount was excessively high for a person charged with a third degree felony. Couch faces up to 10 years in prison for helping her son escape to Mexico, likely in violation of the probation deal.

She needs to be placed under electronic monitoring as a condition of her release, Sheriff Dee Anderson said.
