Tammy Lopez was 37 when she was last seen in Las Vegas on September 1, 2003, in the vicinity of the 300 block of South Casino Center Boulevard. She was described as 5 feet 5 inches to 5 feet 7 inches, 110 to 130 pounds, with blond or strawberry-colored hair and green eyes. Distinguishing features include pierced ears, several scars on her legs, shoulder, and face, and a strawberry tattoo on her lower abdomen; she wore either red-framed glasses or clear contact lenses.

Her case is complicated by a second missing-person report filed in Clio, Michigan, and the Clio Police Department is listed as the primary investigating agency. Authorities have noted she might be in the Seattle, Washington, area, though her last confirmed location was Las Vegas. Very few leads have emerged and the investigation remains active but stalled.

If anyone saw Tammy in Las Vegas, Clio, Seattle, or elsewhere around 2003, or has information about her movements since then, please share what is known with the Clio Police Department.
