The childhood buddies -- Buskirk and Crosley -- had allegedly been talking about raping and murdering someone just to see what it was like.
They are alleged to have done more.
They are alleged to have driven on June 4 to Cirilla's, an adult novelty shop in Terre Haute, and purchased condoms, handcuffs, position restraint straps, and other items.
During conversations with police, Buskirk is alleged to have said the items were purchased to "basically" rape somebody.
The pair, who had been friends for years, also went to Gander Mountain in Terre Haute and purchased rope and a 20-pound weight, which was later found to be bound around Wolfe's body and attached to the rope when her body was pulled from a rural Sullivan County lake on June 10. Her body was recovered by Indiana Department of Natural Resources Conservation Officer divers after they first located it with sonar equipment.
"Jordan Buskirk explained that the initial plan was to rape and then murder (somebody)," Linton Police Department Det. Josh Goodman wrote in the probable cause affidavit. "Jordan Buskirk explained that it was just something that popped in their heads. He advised that it just crossed their heads to try and do it."
Suspects Crosley, from Linton, and Buskirk, from Jasonville, told police that on June 5 they met with Wolfe in the early evening -- about 8 p.m. Crosley stated that he provided her with Valium, the brand name for Diazepam -- a Schedule IV controlled substance at her request, according to the probable cause affidavit.
Later, about 1 a.m. on June 6, they allegedly picked her up again and gave her more "pills" and in Buskirk's words to "see if they could stomach" what they later did, according to the probable cause affidavit.
Buskirk alleged in conversations with police Monday that Wolfe crushed one Valium tablet and snorted it.
Both suspects told investigators that they were also involved "in the trafficking of substantial amounts of synthetic cannabinoid."
Synthetic cannabinoids -- known as Spice and K2 on the market -- are vegetable fibers or plant leaves sprayed with manufactured chemicals that mimic the effect of marijuana, according to Hunterdon Drug Awareness Program's website.
During the investigation, police recovered from Buskirk's 2009 Mitsubishi Lancer, a ledger book, several hundred dollars in cash, material on the floorboard believed to be synthetic cannabinoid and a partial roll of duct tape.
Crosley allegedly told police that the ledger book served as a pricing guide for their illicit drug trade.
Buskirk told police that the actual crime was committed in Greene County, then the tied up, weighted down body was placed in a remote Sullivan County lake near the Greene County line about 3:10 a.m. on Thursday.
Afterwards, both suspects went back to their drug business, according to the probable cause affidavit.
They allegedly drove around to do a drug deal with Wolfe's body in the trunk of the car, but ended up not meeting the customer, according to the probable cause affidavit.
The pair also allegedly disposed of some evidence, including floor mats from the car, Wolfe's cell phone, her glasses and her shoes.
The two men allegedly returned to the lake later in the day to make sure the body had not floated to the surface, according to court records.
Buskirk, who said he had met Wolfe two or three times prior to June 5, changed his initial story to police after failing a polygraph exam. He first told them that Wolfe had accompanied them to Sullivan, but got out of his vehicle near the Marathon Service Station, located at 881 West State Road 154, and walked toward the Sullivan County Courthouse.
However, video surveillance tape from the service station didn't show Wolfe, only the two suspects.
The pair was at the service station for 11 minutes starting at 5:03 a.m.
During the stop, Buskirk opened the trunk and leaned in while Crosley watched. Crosley then went to the rest room and officers noticed what appeared to be mud or soil stains on his pants.
Buskirk then cleaned the car's windshield, put some items in the trash can and both suspects got back in the car and drove off.
During an interview with police at the county jail, Buskirk was asked what runs through his head or thoughts he has regarding what happened.
"Mr. Buskirk explained he has tried to block it out but has thoughts of his son and his parent's disappointment," according to the probable cause affidavit.
Both Buskirk and Crosley are scheduled for initial hearings at 9:30 a.m. on Friday in Greene Superior Court.
