Dominic Castillo was 22 when he arrived in Memphis on January 22, 2017, while on a cross-country backpacking trip from Albuquerque, New Mexico, accompanied by his three-legged dog, Lilly. He was last seen in downtown Memphis; for weeks his family heard nothing from him.

On February 11, 2017, a passerby found Dominic’s body in the cold waters of Nonconnah Creek in Southwest Memphis. Investigators determined he had been strangled and ruled the death a homicide. Lilly was found wandering alone in the days after his body was discovered.

The Memphis Police Department and Dominic’s parents made public pleas for information and CrimeStoppers sought tips, but no suspects have been publicly identified and no arrests have been announced. Does anyone have information about Dominic’s movements in Memphis or who he might have been with in late January 2017?
