Attorney Brian Dell said he filed the lawsuit on 21 June on behalf of his client, Lona Varner, suing the town of El Reno. Mrs Varner's grandson called police on 22 December and said his grandmother was suicidal and may have taken some unknown medicine. Officer Thomas Duran said in a police report that Mrs Varner pulled out a knife and threatened to kill him. The report says another officer used a Taser stun gun on her.
