Lennie Desalle was the second female homicide detective in Philidelphia, after Lilly Rush. She joined the squad in the spring of 2005. Three weeks after joining, Desalle was called to the scene when the skulls of nine women were found buried in the back yard of a house formerly owned by Simone Marks. Detectives Rush and Scotty Valens quickly identified the remains as the victims of Simone's son, serial killer George Marks, who had hunted and killed several women in the woods, taking their heads as "trophies".
