'2 Drunk 2 Care' Tweet Posted Hours Before Car Crash Kills 2

"2 Drunk 2 Care" was the last tweet by Kayla Maria Mendoza before she crashed head-on into a car, killing two people. Now police must decide whether to press charges against Mendoza, who called herself the "Pothead Princess" online.

Mendoza was reportedly driving the wrong way on a highway in Florida early Sunday morning when she crashed into a car containing Marisa Catronio and Kaitlyn Ferrante. Catronio, 21, was pronounced dead at the scene, while Ferrante, 21, died while in transport to a hospital.

Mendoza tweeted "2 Drunk 2 Care" just three hours before getting into her vehicle and the accident. Her Twitter feed was full of pictures of marijuana and joints, causing even more anguish to the families of the victims she killed.

"For someone like her to take my sister's life, the moment I saw that I felt so much anger," Catronio's brother Jesse told CBS.

For now, Mendoza remains free, as no charges have been filed by the police, who continue to investigate and build their case.

Yet for the families of Catronio and Ferrante, life also goes on and they must bury their dead. Ferrante's family told CBS that they had decided to donate her heart and it has already been successfully transplanted.

Family and friends gathered together on Thursday night for a vigil. Ferrante's mother Christine took the time to thank the crowd for their support and offered insight into her life.

"We'll always have an angel watching over all of us, no matter where we are. She just spread happiness all over the place, wherever she went. She made people laugh, people smile. She was selfless," Christine said.

"We're not gonna let Marisa's life be in vain," Catronio's uncle told CBS. "We're gonna try and have some sense of accomplishment, some sense of duty."
