(CBS/AP) BLOOMFIELD, Ind. - The father of one of two southwestern Indiana men accused of killing 19-year-old Katelyn Wolfe says anyone who knows his son knows he couldn't have done it.

NBC affiliate WTHR-TV reports that Gilbert Buskirk also said he was sorry and if he could have stopped the murder of Wolfe he would have. A Greene County judge entered not guilty pleas Friday for 25-year-old Jordan Buskirk of Jasonville and 26-year-old Randal Crosley of Linton. They are charged with murder, conspiracy to commit murder, conspiracy to commit rape and criminal confinement.

According to a probable cause affidavit, Buskirk confessed to police that he and Crosley killed Wolfe. Buskirk's attorney, Jacob Fish, declined comment Friday. A message seeking comment was left Friday for Crosley's attorney, Alan Baughman, by The Associated Press.

Wolfe's father reported her missing June 6 after the teen apparently posting on Facebook that she was being followed. Her body was found a few days later in a body of water in rural Sullivan County and police say she apparently died from asphyxiation. According to CBS affiliate WTHI-TV, she was found bound by rope, handcuffed and with her mouth duct-taped.

A probable cause affidavit reportedly says the men had been smoking synthetic marijuana prior to the attack on Wolfe.

Linton police Lt. Duane Collenbaugh has declined to comment on whether police believe Buskirk or Crosely knew Wolfe, but both men appeared to be listed as Facebook friend's of Wolfe's.

The investigation is ongoing. A pre-trial hearing is scheduled for August 5.
