ST. PAUL, Minn. (AP) _ Prosecutors and defense attorneys disagree over whether there are legal grounds to unlock the cellphone of a woman accused of killing two teenagers and severely injuring a third in an eastern Minnesota crash.

Reports say 32-year-old Rachel Kayl was charged in May with criminal vehicular homicide, second-degree manslaughter and criminal vehicular operation.

The State Patrol says she was driving between 77 and 85 mph in Arden Hills before striking a vehicle carrying three teen girls in December 2016.

Cellular records indicate Kayl wasn't talking or texting at the time of the crash, but prosecutors want to know if she was using the internet or an electronic application. Kayl's attorney says the request to unlock the phone violates her Fifth Amendment rights that prohibit self-incrimination.

A judge will consider the arguments next month.
