And it would turn out it was definitely not the gun that killed Barbara.

And Hayward literally couldn't remember a time when he'd been more frankly shocked and disappointed.

I mean, he really had Richard pegged as the killer.

Richard basically was his only suspect and he was a great one, especially since they had checked on his alibi and it didn't really hold up.

The friends he said he was with that whole day actually said, well, we were with him, but not the whole day.

So basically, there were large chunks of time on the day she went missing when Richard was unaccounted for.

Hayward sighed and reminded himself that, you know, just because the gun he owned wasn't a match, it didn't mean Richard was innocent.

I mean, it's possible he used a different .357 and then just ditched the weapon.

Still, though, Hayward couldn't believe they were back to square one like this.

He felt like he had done everything he could at this point.

He talked to who he needed to talk to, he'd analyzed the evidence they'd gotten, and he had really nothing to show for it.

Hayward was used to closing cases and giving families the answers they wanted, and now he was worried he was not going to be able to do that.

And sure enough, over the coming months and then years, you know, Hayward did continue to investigate this case, but...

But the leads got fewer and fewer, and then eventually he got promoted, and then before long he was pulled into other cases, and eventually Barbara's case just went cold.

In the fall of 2005, so over 25 years after Barbara's murder, Detective Todd Park sat on the floor by his desk in the Salt Lake City Sheriff's Department.

Around him on the floor, it was covered with crime scene photos and interviews and evidence logs from the 1974 investigation of Barbara Rockey's murder.

Park was a brand new homicide detective,

And he had taken on this case after getting a call from one of Barbara's sisters, begging the sheriff's office to reopen it.

And Park wasn't sure if it was maybe just new guy enthusiasm, but he was already pretty obsessed with trying to solve it.

He really wanted to find some answers for the Rocky family, since they'd been wondering what happened to Barbara for now over two decades.
