Met up with a guy who was at Amherst in 1989. He doesn't want me to use his real name because he believes he will one day have to testify in this case, so I'll call him Tim.
Tim got to know Runkle very well in 1989, in the first weeks that Runkle became a teacher at Amherst. He is 100% positive that Runkle talked about the Lake Erie Nature and Science Center. He said Runkle was all over the metroparks, looking for flowers and specimens of all sorts, and spent a lot of time in Rocky River.
Anyway, when Amy was abducted, and the composite sketch of her kidnapper was released, Tim and his friends brought it into school and hung it on Runkle's blackboard. They thought it was funny that it looked so much like their teacher. After Amy's body was discovered, though, the joke wasn't so funny because Tim knew how close Runkle's home was to the location of the body. And so Tim called Bay Village P.D. himself and left a detailed message asking them to look into this teacher.
Flash forward to 2003/2004, when an Amherst detective and a retired FBI agent tracked him down to finally ask him some questions about Runkle. He told them what he knew.
"Do I think Runkle killed Amy Mihaljevic?" he said to me. "Yes, I do."
One of the reasons he feels so sure is that Runkle lies about the Nature Center when asked about it today. "He talked about the Nature Center a lot," Tim says. "He talked about it a lot, until they found her body. After that, he didn't bring it up." Why is Runkle lying?
Other things Tim had to share:
-Runkle told him he knew how to make chloroform. "He said you don't need to order chloroform, you can make it out of 2 household items.
-Runkle frequented parks in Sheffield Lake.
-Runkle lied about why he left Amherst so suddenly. When Tim ran into him at a gas station, Runkle told him that he had left because he got a job teaching high school biology. The next thing Tim knows is the police are asking him about Runkle and telling him that Runkle had turned up on their radar in Florida, after trying to pawn a watch.
-Runkle loved to gossip. And he liked to joke about everything. He joked and gossiped about everything with his kids, says Tim. "Everything except Amy Mihaljevic." When anyone would joke about her, or about how he looked like the composite sketch, it was like someone turned a switch. He suddenly found something else to do. "It didn't register with me until years later what that might mean."
-Runkle joked about keeping a dead body in the refrigerator at school, which was in a little alcove by his room.
-Runkle "seemed to be attracted to the girls in the classroom but also treated them with a little bit of contempt. You could see he coveted them."
-Runkle mentioned housesitting for someone in 1989 and having to take care of their dogs.
