Megan Siobhan Emerick was 17 when she vanished from her Seward, Alaska dormitory in the summer of 1973. On July 7 she was seen walking out of the laundry room and was never heard from again. Her personal effects, including identification, remained in her room, and she was described as 5 feet 4 inches, 120 pounds, with brown hair, hazel eyes and protruding front teeth. She was last seen wearing a white long-sleeved checkered shirt, a brown short-sleeved sweatshirt, blue jeans and suede ski boots.

Her roommate looked for her for three days before reporting her missing to the Seward Police Department. The case is classified as an endangered missing person and foul play is strongly suspected. Investigators have long considered the possible involvement of Robert Hansen, who was known to be in Seward on the day Emerick disappeared; Hansen denied involvement before his death in 2014, but a map found at his home suggested there may have been additional victims beyond those he admitted to.

The investigation remains active and unresolved. If anyone knew Megan, saw her in Seward on or after July 7, 1973, or has information that could help, please come forward.
