(CNN) -- Inside the Charles Manson room at the Museum of Death in Hollywood, Anne Forde looks at crime scene photos from the 1969 Tate-LaBianca murders. 

"I was a kid when he was involved in these crimes," says Forde, who grew up in County Cork, Ireland. "It's just been a fascination for me ever since." 

"His eyes just stand out and look crazy," says Debbie Roberts, who was visiting the museum from Kentucky. "I can see how people followed him." 

A few miles away on Saturday mornings, Scott Michaels is hosting the "Helter Skelter Tragical History Tour." For $65, you can buy a bus seat to see where the murders took place, as Michaels tells the story of Helter Skelter. 

"We have people from around the world that sign up," says Michaels. "We added an additional anniversary tour, which is sold out." 

August 9 marks the 45th anniversary of the murders of Sharon Tate and four others on Cielo Drive in the Benedict Canyon neighborhood of Los Angeles. Tate, who was 8Â½ months pregnant and married to movie director Roman Polanski, was stabbed 16 times as she pleaded for the life of her unborn child. The next night, supermarket executive Leno LaBianca and Rosemary LaBianca were tortured and killed inside their home near Hollywood.

Since then, Charles Manson, who was convicted of orchestrating the murders, has been the focus of continued fascination. 

"People seem to be fascinated by things that are strange and bizarre," says Vincent Bugliosi, sitting in his Los Angeles-area living room.
