LOUISVILLE, Ky. (WDRB Fox 41) -- New pictures and documents released Thursday show Gregory O'Bryan researched the date rape drug GHB on his computer in the days before 18-year-old college student Andrew Compton met him for sex and likely died in O'Bryan's Louisville apartment.
But the prosecutor in the case could not say if police found any GHB at the apartment.
Also, investigators have examined computers belonging to each man, helpful because O'Bryan said they met online through a gay dating site.
"We have discovered forensic examination of computer hard drives both of the victim and defendant and turned over contents of those to defense counsel," said Tom Van de Rostyne, Asst. Commonwealth's Attorney.
Documents also show prosecutors found child porn images and video on O'Bryan's computer and a flash drive.
Also, blue or purple dots on certain pictures show how police used a special, luminous spray and black light to see where blood may have been wiped away from O'Bryan's bathroom sink and from the trunk of his car.
O'Bryan faces murder and other charges.
He told police Compton died during sex, perhaps after Compton broke his neck in a "strange position" on a couch.
Other pictures show cleaning liquids, insect and bedbug killer, syringes and sex toys taken from O'Bryan's apartment.
Evidence also includes children's underwear; handwritten notes about various drugs and their effects on one's libido; notes with screen names and passwords for several gay sex dating sites and screen names, emails and phone numbers of likely users of those sites.
"We're trying to construct the DNA profile of Andrew Compton because we do not have Andrew Compton's body we have to use his parents DNA to construct a profile of him to test different things we think may be relevant in case," said Van de Rostyne.
O'Bryan told police he put Compton's body in a cardboard TV box and put it in a dumpster.
Police searched a southern Indiana landfill for two weeks, but could not find it.
