BURWELL, Neb. (AP) — A memorial service has been held for a Burwell teen killed last weekend in a rollover crash.

Authorities say 16-year-old Bryanna Izaguirre, a sophomore at Burwell High School, died after a pickup carrying her and three other teens crashed late Friday in north-central Nebraska east of Burwell.

Izaguirre was pronounced dead early Saturday at Valley County Hospital in Ord. A memorial service was held Wednesday morning at Sacred Heart Catholic Church in Burwell.

Investigators say the pickup left a gravel road, rolled and hit a tree.

The 17-year-old driver from Ericson and two other 17-year-olds suffered minor injuries and were treated at a local hospital.

The crash remains under investigation by Garfield County authorities and the Nebraska State Patrol.
