Thirty-one-year-old's Brandy Teague $600,000 bail was upped to $1 million because a judge determined Teague posed a flight risk and a risk to her children.
According to police, Teague may have fallen asleep moments before her 2010 Hyundai Accent veered off Broadway between First and Second streets about 9:45 p.m. last Saturday.
Teague's three children -- ages 2, 3, and 10 -- were badly hurt and taken to Rady Children's Hospital, where 3-year-old Carlee Ramirez died.
Teague was treated at a hospital before being arrested. She faces more than 23 years in prison if convicted of manslaughter, DUI with injury, child endangerment, driving on a suspended license and methamphetamine possession.
She will be back in court next Thursday for a readiness conference and April 23 for a preliminary hearing.
Ramirez's funeral will be held Tuesday.
