Lucas Zavala, 19, disappeared while attempting to cross from Sonoyta, Mexico, into Lukeville, Arizona, sometime between July 16 and July 19, 2009. He reportedly became dehydrated and exhausted after walking about eight hours and was left near a highway; nothing definite is known about what happened to him after that.

Lucas is described as a Hispanic male with black hair and black eyes, standing between 5 feet 3 inches and 5 feet 7 inches and weighing 140 to 160 pounds. He had pierced ears and a distinctive scar on his left knee from a machete cut, a line with three dots. At the time he went missing he wore a black sweatshirt with a white neck, faded blue jeans and either white sneakers with black stripes or yellow boots, plus a black leather belt with a silver-buckled image, a blue scapular showing the Virgin Mary, and carried a school backpack with a watch in his pocket.

The Pima County Office of the Medical Examiner is listed as the investigating agency. Few public details are available about Lucas’s movements after he was left by the highway. If anyone saw Lucas in that area in mid-July 2009 or has information about his route, please come forward.
