Lover's Lane Killer - Atlanta Murder Mysteries

Beginning in early 1977, a serial killer stalked couples in Atlanta, killing like clockwork on a three week schedule. Survivors said he was heavy-set and muscular, and papers reported that he either switched up his methods - or that there were multiple killers that fell under the same case, mainly owing to the observation that the earliest murders were ambushes of single people.
The killings stopped abruptly, after a half-dozen victims were created, and APD has never found any real clues.

I haven't looked at the Lovers Lane stuff but the morning commute to the hospital route is 100% Atlanta Child Murders related.
