The bodies of three men have been found in the southern Arizona desert and all appear to be heat-related deaths, federal authorities said.
Casa Grande Station agents discovered two bodies near Quijotoa, according to U.S. Border Patrol officials.
They said the bodies and three marijuana bundles were spotted Friday by air patrols.
The Tohono O'odham Police Department took custody of the scene.
Tucson Station agents reported finding the body of a man Saturday near Arivaca within 100 yards of a road.
The man's sister told agents her brother had fallen and was unresponsive before being abandoned by the group crossing the desert.
Authorities said the nationalities of the three men aren't immediately available.
In the past nine months, Border Patrol agents have reported close to 100 deaths throughout southern Arizona.
Residents can report suspicious activity to the Border Patrol and remain anonymous by calling 1-877-872-7435 toll free.
