SAN DIEGO -- Jurors in Richard Tuite's murder trial watched Wednesday more videotaped interrogations from one of the teenagers who originally confessed in the case.

In the 1998 interview, 15-year-old Joshua Treadway insisted he told police everything he knew about the murder of Stephanie Crowe. But interviewers claimed a voice-stress machine showed he knew more.

Attorneys for 34-year-old Richard Tuite are showing jurors the tapes, in an effort to prove Treadway, Michael Crowe and Aaron Hauser killed Stephanie Crowe.

They will show about two more hours of videotape Wednesday, then move on to testimony from one of the main detectives in the investigation.

Tuite was charged with murder in 1999, after investigators found Stephanie's blood on his sweatshirt.
