While investigators are not calling those two people -- a man and a woman -- suspects, they would like to talk to them about the death of Douglas Engstler, who was found by a relative in his home near Cave Creek Road and the Carefree Highway earlier this week.

At this point, detectives have not said how Engstler, 63, was killed. They've been very tight-lipped about all aspects of their investigation.

In addition to the photos of the man and the woman, the sheriff's office has also released pictures of two cars. Detectives believe those vehicles are connected to the two people of interest, but they're not saying how.

Investigators have not released any details about the photos, other than that they were taken outside a Phoenix convenience store.

If you have any of information about the people or vehicles in the photos, you're urged to contact the sheriff's office.
