DENVER (AP) — The family of a slain pizza deliveryman and a wounded Texas sheriff's deputy are among those in federal court in Denver for the sentencing of the woman who bought the gun used in their shootings and the killing of Colorado's prisons director.

Twenty-three-year-old Stevie Marie Anne Vigil is scheduled to be sentenced Monday. She faces a maximum of 10 years in prison for giving prison gang member Evan Ebel (EE'-bul) the gun used to kill prisons chief Tom Clements nearly a year ago.

Prosecutors say Ebel used the same gun to kill Nathan Leon, a Denver computer technician and pizza deliveryman, and wound a sheriff's deputy in Texas, where Ebel fled. Ebel was killed in a shootout there.

The judge is allowing Clements' widow, Lisa Clements, Leon's relatives and the Texas deputy to testify about their losses. Lisa Clements has been largely silent about her husband's death and it was unclear Monday if she planned to address the court.
