In December 1985, a narcotics detective was shot and killed in the driveway of his farm in Pueblo, Colorado, where he lived with his five children and his wife, Donna Yaklich. Initially, authorities suspected Dennis' death was linked to his work in law enforcement, but a tip led them to two teenage shooters - and eventually, back to Dennis' wife, Donna. However, attorneys for Donna Yaklich argued that Dennis had been beating his wife. The murder, they claimed, was a battered woman's desperate attempt to escape a lifetime of abuse - or potentially becoming a murder victim herself, like Dennis' first wife, who is thought to have died of a diet drug overdose in 1977.
