Philip Liberty, a 75-year-old retired IBM executive, was found dead in his Austin, Texas, home on November 19, 2015. The scene was reported as exceptionally gruesome: he had been shot in his living room and his body was later dragged to the garage. An autopsy determined the cause of death was a gunshot wound to the face.

Investigators encountered early obstacles — there were no signs of forced entry and nothing appeared to have been stolen. Attention shifted to his friend Irwin Ernie Pentland after reports that Pentland had picked up Liberty’s grandson from daycare the day before the murder and that forged checks totaling about $20,000 had been presented in the days around the killing. No immediate additional suspects are described.

What details might someone who knew Philip or his routine remember that could shed light on his final days?
