The investigation remains on hold, into the Sunday morning shooting death of Draper Police Sargeant Derek Johnson.

Police suspect a 35-year-old transient of shooting Johnson...along with a female -- who was with him -- and himself. 

The woman, and suspect, each survived...and police are now awaiting their recovery, so they can be questioned.

Johnson, 32, will be honored Friday, with funeral services at the South Town Expo Center.  An estimated 5-to-10-thousand people are expected to attend.

The slain police officer leaves a wife and 6-year-old son.
