Update: Kayla Mendoza, 21, who is accused in the wrong-way, DUI-related deaths of two Florida women last year, was ordered held on a $600,000 bond during a court hearing Tuesday afternoon. If Mendoza is able to post bond, she can't leave her home except for medical reasons. She's also prohibited from traveling outside of Broward County without the court's permission and from obtaining a passport, the Sun-Sentinel reported.

Original story begins here:

With her face covered, Kayla Mendoza was wheeled into Broward County jail on a stretcher Monday after she was arrested and charged in the deaths of two Florida women killed in a head-on crash in November on Sawgrass Expressway. Just hours before the wrong-way crash, Mendoza is believed to have tweeted “2 drunk 2 care,” authorities said.

The 21-year-old woman was charged with two counts of DUI manslaughter while impaired, two counts of DUI manslaughter with an unlawful blood alcohol level, two counts of vehicular homicide, and two counts of driving without a license and causing death, the Florida Highway Patrol said.

Mendoza, who was 20 on the night of the crash, registered a blood alcohol level of .15, nearly twice the .08 legal limit, according to the FHP search warrant. The crash killed best friends Marisa Catronio and Kaitlyn Ferrante, both 21.

Members of both families were there when Mendoza was rolled into the main jail on a stretcher early Monday evening. Christine Ferrante, Kaitlyn's mother, told the Sun-Sentinel that Mendoza covered her face "so we couldn't see her and she couldn't see us.

"All this time, I wanted to see those gates close behind her, and now I have," Ferrante continued.

Mendoza was being held without bond, according to jail records.

The accident occurred around 1:45 a.m. on Nov. 17, a Sunday night, when Mendoza drove head-on into the women's Toyota Camry, FHP said. Kaityln, who was driving, suffered severe head injuries. She was placed on life support before being pronounced dead days later at a Broward hospital. Marisa Catronio was killed on impact. “We’re not gonna let Marisa’s life be in vain," her uncle, Ron, told CBS Miami, shortly after the accident. "We’re gonna try and have some sense of accomplishment, some sense of duty.”

Gary Catronio, Marisa's father, said at the time, “I didn’t need a blood alcohol test,” in reference to Mendoza’s blood alcohol level. “This person was drunk and on a suicide mission.”
