Nancy Langert, 25, and her husband Richard Langert, 28, were shot dead in their Illinois home on April 7, 1990. Sixteen-year-old David Biro was found guilty of the murders. What made the grieving process even more difficult for the families was the fact that Biro wouldn’t admit to the murders and therefore would not say why he did it. Twenty-three years after the murders, Biro finally confessed via a 15-page letter from jail, addressed to Nancy’s sister Jeanne Bishop.
The Langerts murders was not the first time troubled teen Biro held a gun. According court records obtained by The Chicago Tribune: “David Biro used a BB gun when he was 13 to shoot at a 7-year-old boy; later, he shot at the windshield of a car and was accused of stealing a bicycle lock from a sporting goods store. Just after Biro’s 14th birthday, his family found a stolen motor scooter in the basement. Around the same time, they noticed a strange substance in their milk.” Biro was admitted to an in-patient psychiatric facility but after several weeks he left “on a pass and refused to return.” In 1987, he started his freshman year of high school. 48 Hours will air its interview with Nancy’s sister Jeanne Bishop, who now believes Biro deserves a second chance, on November 28 at 10pm on CBS.
