It's February 21, 1994.

27-year-old Helen Chevalier miraculously makes it home after a harrowing night.

Helen works the street as a prostitute to pay for her drug addiction.

The night before she luckily escaped the clutches of a john who refused to let her out of the car and kept pulling her by her hair.

24 hours later, Helen leaves her home, saying she's going out to meet a friend.

She would never be seen alive again.
