This is my first post, and I really don't know how to go about laying this out, so here goes:
I've been looking into an ex Hialeah Police Officer the past 6 months or so, Marc Leroy Holliday (died September 2000). He was fired in 1973 for harboring a 15 year old runaway on his boat at Dinner Key Marina and in his apartment on Key Biscayne, but was later reinstated, only to be fired in 1976 for falsifying an arrest report.
In 1978 he was arrested for raping and robbing a 15 year old girl, however, he was acquitted due to prosecutorial misconduct. He was defended by renown defense attorney Roy Black. When arrested he mentioned "The Canal Murders", 12 unsolved homicides of females in Dade and Broward counties in 1975 and 1976, which is how he popped up on my radar, I was looking into those cold cases.
Marc Leroy Holliday (MLH) moved to California sometime in 1979 or 1980 (he had lived there as a child) and kidnapped a 5 year old girl in Palm Springs in November of 1980, and a 4 year old girl from Indio in early 1981. He let both girls go, the 4 year old was not sexually assaulted, the 5 year old Palm Springs girl was however.
Before being sentenced he told two different psychiatrists that he abducted many young women, mostly hitchhikers, for his own sexual gratification. He said the oldest was 15.
I contacted one of MLH's ex wives a couple months back, and she had no idea about any of the 1978 Florida stuff or any of the California stuff. She said that as soon as they got divorced she moved somewhere else in the state. She did however say a couple things that stood out:
After she moved she said some detectives came and got a gun of hers that she had owned while they were married (it was later returned to her).
While telling me how surprised she was about the young ages of the California girls she said she wasn't as surprised about the 1978 case, and said that MLH had a disdain for prostitutes.
She told me that "he got a little crazy with her". When I asked her if she wanted to elaborate, she said "he knocked her around".
So now that the backstory is out of the way, here's why I had to come here and post this.
-MLH's boat was docked at Dinner Key Marina, LESS THAN A MILE from where Amy went missing.
-His apartment was ~5 miles from where Amy went missing.
-In 1974 when Amy went missing it looks like MLH's job was in limbo, and it doesn't seem like he had been reinstated yet.
-MLH was a Narc Officer with Hialeah until they dissolved the Narc Squad.
-In Susan Billig's book it says the bikers would convene at Dinner Key Marina before driving North to Daytona for Bike Week.
-MLH's ex wife and an ex co-worker of his who I've been in contact with said everyone thought he died in the early 1990's. The following is speculation, but according to the ex co-worker, he thinks MLH or his family kind of floated that bad info back to Florida on purpose.
Did he see the bikers coming through town and think that this was a perfect opportunity?
