As police continued their investigation, one of Bart's friends gave them the breakthrough they needed. After being brought in for questioning, 21-year-old Steven Champagne confessed Bart had convinced him and another friend, Christopher Brashear, to kill Bart's family. Police were ready to close in, but Bart disappeared.
More than a year later, a tip led authorities to Mexico. There they found Bart living under an assumed name. Bart had been working at a furniture store and had dated his boss's daughter. Bart was arrested, taken back to Texas and put on trial. He was convicted of capital murder and sentenced to death.
