With movie star looks, a great career and a successful boyfriend, Jennifer Schipsi seemed like the girl who had it all, until her life came to a tragic end. Police believe she was strangled to death by her boyfriend, local business owner Bulos "Paul" Zumot, who then allegedly staged a fire in the home they shared to cover up the murder. The two had a tumultuous past with a history of domestic violence� but would evidence show that Paul murdered Jennifer?

Jim Avila's report includes exclusive interviews with both the families of the victim and of the defendant, as well as unique evidence, including a never-before-heard recorded telephone call from Jennifer, a never-before-seen interrogation tape and other items the jury never saw.

The exclusive report airs on "20/20" on FRIDAY, MARCH 25 (10:01-11:00 p.m. ET) on the ABC Television Network.
