A Natrona County man will be spending time behind bars after he was convicted of sex crimes against a number of victims.

Shaun Hamilton was sentenced to 50-to-56 years in prison, after a jury found him guilty on one count of first degree sexual assault, one count of first degree sexual abuse of a minor, and three counts of second degree sexual abuse of a minor.

Investigators with the Casper Police Department say in January 2015, the then 12-year old victim described what had happened, and said Hamilton was the one who did it.

Detectives collected DNA evidence from the scene where the crime was alleged to have occurred, and the DNA was later identified as Hamilton’s.

The victim's DNA was also found on a swab taken from Hamilton.

Another victim claimed she also was assaulted by Hamilton back in 2009, when she was 18, and provided a written statement for police.

In closing arguments of the trial, the prosecution said the defense had no reasonable argument that one victim was trying to frame Hamilton, and that the victim showed investigators exactly where all the evidence was at the time.

As for the other victim, the defense questioned why she waited so long to report the crime to police, but the prosecution countered that there is no statute of limitations, when it comes to sex crimes.

The defense also made mention of some inconsistencies in the victim's recollection of events, but one doctor testified that people trying to recall traumatic events, can sometimes have difficulty remembering specific details and the chronological order of events.

Hamilton's actual sentence was 32-36 years for first degree sexual assault, and 10-15 years for first degree sexual abuse of a minor.

Both of those sentences will be served concurrently, or at the same time.

After that, he will serve three 18-20 year concurrent sentences, for the three counts of second degree sexual abuse of a minor.
