(CBS) BLOOMFIELD, Ind. - Two drug dealers, who were childhood best friends, killed their 19-year-old customer, Katelyn Wolfe, after a plan to rape and murder just "popped in their heads," according to an affidavit obtained by Crimesider.

Jordan Buskirk, 25, of Jasonville, Ind., told police, according to the affidavit, that he had only met Wolfe two or three times before and that she was not the intended target but "the opportunity was just there."

During a police interview, Buskirk allegedly admitted that he and 26-year-old Randal Crosley, of Linton, Ind., had conversations about forcing themselves onto a complete stranger for at least a week before Wolfe's June 6 murder. In the days prior to the murder, police contend, Buskirk said the two men purchased condoms, handcuffs, rope, a 20-pound weight, and other items to use to execute their plan.

Crosley and Buskirk are charged with murder, conspiracy to commit murder, conspiracy to commit rape and criminal confinement in the murder of Wolfe. A Greene County judge entered not guilty pleas Friday for both.

Wolfe's father reported her missing the night of June 6 after he saw a message posted on Facebook at approximately 3 a.m. earlier that day reading, "Trying to party looking for fun. Out on a walk with creeps that keep driving by."

Through use of phone records, police say they were able to contact several people thought to be in communication with Wolfe around the time of her disappearance. Randal Crosley was one.

After initially avoiding detectives' phone calls, according to the affidavit, police went to Crosley's home and interviewed him. It was then that he allegedly told officers that Wolfe had sent him a text message on the night of her disappearance reading, "Out walking trying to avoid strange drunks lol looking to party." The messages continued, "Get here fast dude this car has driven by me four times."

According to the affidavit, Crosley told police he and Buskirk met with Wolfe at approximately 8 p.m. in Linton to sell the teen Valium.

Investigators say they determined Crosley's phone was in the same general location as Wolfe's, later that night, around the time of her disappearance.

Crosley and Buskirk made statements that were inconsistent with the facts, the affidavit says.

On June 10, Wolfe's body was found submerged in a lake in Sullivan County, Ind. Wolfe's body was found with a white shirt over her head and she was bound in duct tape and rope with an anchor attached, the affidavit says. A medical examiner later ruled the cause of death to be asphyxia due to smothering.

Later that day, Buskirk agreed to speak with detectives and, police say, described in detail the events that took place the night of Wolfe's disappearance.

According to Buskirk's account, as outlined in the affidavit, the two men met with Wolfe twice that night, both times to sell the 19-year-old prescription pills.

During the second transaction, the three traveled to a county road in Buskirk's car and that is where the murder allegedly took place. The affidavit alleges the two men had sexual intent when they first began to restrain Wolfe but the situation unraveled fairly quickly and a struggle ensued. According to the affidavit, Buskirk told authorities that Crosley began saying over and over that Wolfe needed to die. The 19-year-old was then choked, handcuffed, and bound with duct tape, the affidavit says Buskirk told police.

The two men then put the teen's body in the trunk and proceeded to drive around getting high while sending text messages from Wolfe's cell phone and posting updates to her Facebook page in an attempt to cover their tracks, the affidavit alleges.

The men later drove to a remote location in Sullivan, Ind. and disposed of Wolfe's body at around 3 a.m. by throwing it off of a hill into a lake. Evidence was allegedly sporadically dispersed by the men throughout the night.

The affidavit cites Buskirk as having a son and Crosley as being married. Buskirk reportedly told authorities he has tried to block out the crime but has thoughts about his son and his mother and father.

Attorneys for Buskirk and Crosley could not immediately be reached for comment.

A pre-trial hearing for the pair is scheduled for August 5.
