Heather Quast

WEST JORDAN — A 22-year-old man convicted of murder by a jury was sentenced to prison Monday in a stabbing death that stemmed from a drug deal.

Cristian Alzaga was ordered to serve concurrent sentences of 15 years to life for murder and five years to life for aggravated robbery, both first-degree felonies, in connection with the May 2010 killing of Heather Quast, 18. Third District Judge Bruce Lubeck also sentenced the man to one to 15 years in prison for aggravated assault, a second-degree felony. That sentence is to run consecutive to the murder charge.  

Alzaga was convicted by a jury in February.

On May 26, Quast and a friend, Aric Russom, 21, were in a field next to the Jordan River Parkway Trail, near 1100 West and 3900 South, waiting to make a drug deal when they were both stabbed, police said. Russom was stabbed in the face, near his eye. Quast was struck in the stomach and was taken to the hospital, where she was later pronounced dead.

Both Alzaga and Jose Jesus Neri, 21, were charged in connection with the slaying days after the incident. It is believed Neri was responsible for arranging the drug deal that led to Quast's death.

Neri's case is scheduled for a pre-trial conference April 2.
