Ever since his incarceration, it has been speculated that Ihde was responsible for additional murders that occurred in the San Francisco Bay Area, and most prominently has been suggested as an alternative suspect in the death of Bibi Lee.
For this crime, he was convicted on charges of forcible rape and assault with intent to commit murder and sentenced to six years imprisonment.
However, it would later be revealed that his move to the area flew under the local police's radar, supposedly because the list of registered sex offenders was not exchanged between departments at the time.
Not long after his arrest, he was linked to the murder of 68-year-old Ellen Viola Parker, a retired nurse who was found sexually assaulted and strangled at an unfinished condominium in Vancouver, Washington on February 24.
In his testimony, he claimed that he asked Parker to give him a ride home from a grocery store, after which he raped and strangled her before stealing her car keys and purse.

[9] Prior to jury deliberations, his attorney argued that the evidence was circumstantial and reliant on the testimony of a jailhouse informant, and that his client had converted to Christianity while in jail, helping other inmates.
Connell's killer was identified via DNA as Robert Boyd Rhoades, who by the time of identification was already on death row for the 1996 torture-murder of 8-year-old Michael Lyons in Yuba City.
