Arrest made in 1998 Frisco sexual assault and kidnapping case

A stairwell attack that sat unsolved for 28 years finally broke open when Colorado investigators matched preserved DNA from the Frisco scene to 67-year-old Arnold Eugene Elisha. The arrest, announced June 5 by the 5th Judicial District Attorney’s Office, Frisco Police Department and Colorado Bureau of Investigation, turned a long-dormant file into an active prosecution.

The case dates to February 6, 1998, when a 16-year-old girl was assaulted in a stairwell at a condominium complex in Frisco, Colorado. Investigators collected DNA at the scene, but for years the evidence did not produce an arrest. CBI said newer DNA methods generated fresh leads from the original profile, and a later sample taken from Elisha reportedly matched the evidence preserved from 1998.

Prosecutors charged Elisha with first-degree kidnapping, second-degree kidnapping, first-degree sexual assault and first-degree sexual assault with a deadly weapon. At his first appearance, the judge set bond at $2.5 million cash or surety, and his next court date was scheduled for June 15 at 2 p.m.

The original case details show how much investigators had to work with from the start and how little they could close around a suspect at the time. According to local reporting, the victim was from Kansas and was visiting a friend in Frisco when she was attacked after using a hot tub at the complex. Witnesses told police a man had been loitering around the hot tub area before the assault, and the victim reportedly told officers the man’s name may have been “Arthur.” None of that was enough to lock the case down then. The DNA was.

The arrest also lands as Colorado keeps trying to dig out from a long-running backlog in sexual-assault evidence testing. In February, CBI said it was pushing toward a 90-day turnaround time for forensic medical evidence by September 2026. The agency said its DNA section had 19 testing scientists, with more in training and additional retirements and leaves expected this year, and said the average testing time for sexual-assault cases had dropped from 450 days in June 2025 to 190 days in January 2026.

For Frisco, the big change is simple: what began with a stairwell, a hot tub area and a possible first name now has a suspect, a DNA match and a court date. The evidence that survived 1998 is the evidence that finally made the case move.
