Clair Owen Pollard, an 80-year-old retired rehabilitation professional, was found dead in his Norman, Oklahoma home on the morning of November 21, 2011. Neighbors had known him as an active community volunteer and former University of Oklahoma staffer who often walked his dog and helped others. Family members found him inside his house on the 2200 block of Barton Street and called police, who arrived about 8:40 a.m. and described clear signs of a struggle.

Investigators say two men, 19-year-old Brandon Ke Reed and 58-year-old Billy Dean Battenfield, came to Pollard’s home around November 20 and attacked him, using more than one weapon and leaving him fatally wounded. Credit cards, jewelry and other items were taken; surveillance images later showed two men using Pollard’s stolen cards. Reed admitted taking part in the attack and in using the cards. Both men were arrested on November 23, 2011, and prosecutors filed first-degree murder charges. Battenfield’s criminal history, including prior murders and a 2011 parole from a New Mexico prison, drew sharp attention as the case proceeded.

Did anyone in Norman know Pollard well enough to recognize those surveillance images or recall him offering help to strangers in late 2011?
