Lona Varner's grandson called 911 and told the dispatcher that his grandmother "wanted to end her life."
Officer Thomas Duran writes in a police report that Varner pulled a kitchen knife from under her pillow and threatened to stab and kill him if he tried to take her from her home.
The report says another officer used a stun gun to subdue her.
Varner's attorney says she's asking for at least $75,000 in damages.
