Police said Tuesday the crash was not the result of drag racing.
Denise Cavada, 48, was driving home from a bingo game around 10 p.m. on Aug. 26 when another vehicle smashed head-on into hers near Golf and Shermer roads, police said.
Cavada's vehicle split in half. Witnesses said they saw a man jump out of a vehicle and run away. No one is in custody.
Cavada's niece said the victim is survived by a daughter and two sons, who live out of state. Her relatives said the family is having trouble paying for funeral arrangements. They set up a GoFundMe campaign and asked for support.
