New chilling details have emerged about alleged Golden State Killer Joseph DeAngelo's trophy filled bedroom.
Criminologist Paul Holes has given a chilling insight into the suspected mass killer's lair in Sacramento.
The cold case investigator revealed the details on My Favorite Murder podcast after he visited the home.
DeAngelo, 72, is believed to be responsible for at least 12 murders and more than 50 rapes in California between 1975 and 1986.
Holes claimed that the killer would turn on the television, only to turn the sound off and place a towel over the screen 'so he would have this glow, so he could see her.'
The Golden State Killer was known to bind his female victims and place them in front of TVs.
There were also jewelry, cuff links, necklaces and heart shaped pendants found inside.
"I'm looking at that going, 'Is that just a dust cover? Or is he reminiscing (and) he wants a glow, you know,?'' Holes revealed.
"Is he pulling out any of those souvenirs and replicating the glowing environment from back in the 1970s?"
Also taken from the home in the Citrus Heights suburb were ski masks believed to have been worn during the attacks and murders.
Retired DeAngelo, 72, was living alone when he was arrested by detectives, after DNA evidence linked him to the crimes.
The police have now finished removing evidence from the single story home but retired cop DeAngelo did not co-operate during the search.
Holes claimed that DeAngelo was extremely uncooperative while being investigated after his arrest.
"I watched seven hours-worth of the interviews, and I just don't see him talking,' Holes added.
"He's a psychological sadist – his big thing was the fear he was instilling in the victims."
