Boone County - A convicted child killer says he expects prosecutors to charge him soon in the 20-year-old abduction case of 6-year-old Shannon Sherrill of Thorntown. 48-year-old David Penton is in an Ohio prison convicted of murdering a 9-year-old.

The Sherrill disappeared from her Thorntown home in 1986. Private investigator Mark Harper has worked with the Sherrill family on the case since 2003.

"We know that the case is in the prosecutor's hands and we're looking for an indictment sometime soon," Harper told Eyewitness News by phone.

The Boone County Prosecutor didn't return our calls regarding these latest developments in the case.

Penton's name surfaced after a former cellmate sent a letter last year to Boone County authorities saying he had information in the case. Penton tells the Tyler Morning Telegraph that an Indiana State Police investigator interviewed him in prison as recently as last month. Penton said he expects to face charges in Shannon Sherrill's death.

"I'm not going to pretend to be a saint. I've done wrong in my life. I'm not going to pretend that I haven't done wrong. But I can't convince anyone that I'm not running around the country killing young girls," said Penton.

Penton pled guilty to three murders in Texas and one in Ohio. Investigators from several states are reportedly looking into as many as 25-30 additional child killings. Penton allegedly told cellmates he's committed 50 murders.

Members of Shannon Sherrill's family say they been told by Indiana authorities not to discuss the case.

Shannon's father Mike Sherrill recently suffered two major heart attack and holds out hope that the individual responsible for his daughter's abduction, will soon be brought to justice.
