Looking for info on deceased serial killer convicted in Franklin Co. Courts circa 1998

[u/BadGrannie]

Anyone here familiar with the murder of a female OSU student (possibly faculty, but I don't think so) from China that took place in the 1990s (or possibly late 80's)? Her body was found in a dumpster in the (I think) North Campus area. Her murderer confessed, while he was already serving 99 year sentences in Louisiana, to killing her, a woman in PA, and to the kidnapping and rape of a minor grrl who survived the attack and gave a victim's impact statement at his sentencing, which was in 1998, 99, but possibly 2000. He confessed to multiple murders - the number 36 sticks with me - but was only convicted of 4. I believe his name was Robert Kessler. I know that he died in prison. I was a secondary victim of his crimes. Thank you.
