Jeff's defense attorney, Alan Baum, brought his own experts in to attack the prosecution's timeline and the time of death, which police put at 5 p.m. Saturday. Baum said there was definitely "some human activity in that house after, long after Jeff left."
"20/20" gathered the jurors together to talk about the trial and the limited circumstantial case. Ironically, it wasn't the police timeline that brought the jurors to their conclusion.
According to one juror, "What stood out for me was a picture of Rev. Bob Pelley. A photograph of his body laying in the house, the manner in which it was laying … led me to believe that the shooter came out of Jeff's bedroom."
And there was another photograph the jurors found significant, of a gun rack in the parent's bedroom. No gun -- just a gun rack -- but combined with Jeff's stepsister Jessica's testimony, it became critical because she remembered both a bow and a gun in the rack Friday night.
In the jury room, there were three votes over 2½ days, and with each ballot, the tally for innocent shrank until everyone agreed that Jeff had committed the crime.
A murder spree that took four lives was finally solved without the high-tech CSI or DNA evidence. A prosecution depended upon the old saw of motive and opportunity, and a community determined not to forget the minister, his wife and their two little girls.
Jeff is appealing the verdict. He is currently sentenced to 40 years for each murder, for a total of 160 years.
Jacque Pelley, Jeff's sister, is looking for anyone with information that might help exonerate her brother. Please visit www.JusticeforJeff.org to contact her.
