Sleepless nights have been haunting Mary Hernandez ever since Valentine's Day.
"I just want to wake up. This is a nightmare," Hernandez said.
Sunday night, her daughter, 18-year-old Megan Hernandez was on a Valentine's Day double date with boyfriend, 20-year-old Travon Wilkerson, friend Jamie Booker, 21, and her boyfriend Daeshaun Dorsey, 20.
After a night at the movies, they left for home.
Early Monday morning, on southbound 99 near the 12th Avenue exit, they were involved in a crash.
"A drunk man just hit us," said Booker, who survived the crash.
That man was Rodney Thurman, who investigators said ran from the scene.
"It was wrong for him to run. He could have helped us. It could have been a whole different situation. She probably could have been alive right now," Booker said.
Thurman later turned himself in, but not before Megan Hernandez died.
Her boyfriend of two years, who survived the crash, says he feels lost.
"Her spirit. Her everything. She was the best thing in the world," Wilkerson said.
Mary Hernandez recalled the last conversation she had with her daughter. She said Megan had saved up to get her a special Valentine's Day gift.
"'Oh, I found something, you're going to love it.' She said, 'I'm going to get it mom,'" Mary Hernandez said.
She wouldn't tell her exactly what it was -- just hints.
"'My index finder is your ring finger.' She said, 'If I buy you this, you better not lose it. I will never buy you another Valentine's Day present.'"
The Hernandez family has yet to collect her belongings at the Sacramento Coroner's Office.
But in it, they expect to find a special ring.
"It is the Valentine's Day present I get from her. It's the last everything," Mary Hernandez said.
Friends and family gathered at the 5th Avenue overpass where they released balloons.
They promised her, while the balloons may fly far away, Megan will forever stay close to their hearts.
Megan Hernandez is survived by her mother, Mary, and twin brother, Patrick.
