On New Year’s Day 2015 a drive-by shooting in a New Orleans neighborhood killed 64-year-old Desmond Lange Sr. and his 42-year-old son Desmonde Lange Jr. The two men were standing by their pickup truck in the driveway of the family home when an assailant in a vehicle opened fire and then sped away. Neighbors and relatives described the Langes as good people; the elder Lange worked as a housing rehabilitation supervisor.

The double homicide compounded an earlier loss for the family: in 2005 the youngest son, Jeffrey Michael Lange, was shot and killed while driving his car at age 29. Immediately after the 2015 shooting the New Orleans Police Department said the investigation was ongoing and that no motive or suspects had been identified. Subsequent reporting has not revealed arrests or the identification of suspects, and the case appears to have gone cold.

Does anyone have information about the 2015 shooting or memories of the Lange family that could help bring answers?
