Both of the previous convictions were overturned on appeal and a new trial was ordered for Camm,accused in the shooting death his wife Kimberly and their children Bradley, 7, and Jill, 5, in the garage of their Georgetown, Ind. home in September of 2000. Camm had been a state trooper for more than a decade and left the force about four months before the murders.

There was applause and weeping in the courtroom as the verdict was read. Camm rocked back and forth, holding his head in hands and crying.

After the verdict, according to Camm's sister Julie Blakenbaker, Camm leaned against the wall and said it was "good," but that he still didn't have "them," referring to his family. Kitty Liell, Camm's attorney at his second trial, said that "prayers have been answered."

Camm has always  maintained his innocence, saying he was playing basketball with 10 other people.

The jury began deliberating Tuesday at the courthouse in Lebanon, Ind. after getting the case Monday evening.  Camm's third trial was held in Boone County northwest of Indianapolis because of pretrial publicity in southern Indiana, where the Camms lived in the Louisville, Ky., suburb of Georgetown.

Camm's defense argued another man - Charles Boney - was the killer, and acted alone. Boney has already been convicted of murder in the case, reports CBS affiliate WISH-TV.

A judge allowed evidence to be admitted at trial that DNA linked Boney to the scene, reports the station. Prosecutors had argued that the evidence wasn't reliable.

On Wednesday, jurors asked to see 20 pieces of evidence including the police interview with Camm and the T-shirt that he wore the night his wife and children were shot to death, reports the station.

The jury in Camm's first trial took 30 hours to reach a guilty verdict. The jury at the second trial deliberated for 45 hours.
