A woman involved in a crash in Lewiston that left her daughter and the infant’s father dead has also succumbed to her injuries.

Police say 20-year-old Tyrell Willigar of Brunswick died after he went off the road on Grove Street around 10:45 p.m. Wednesday night and crashed into a tree.

7-month-old Kinsley Willigar died at Maine Medical Center last Thursday, while a hospital spokesperson said Monday her mother, 20-year-old Adaysia Reed, had also died from her injuries.

The crash is still under investigation but police say speed was a factor.
