Three decomposing bodies were found by Tucson Sector Border Patrol agents in the desert over the weekend.
Agents discovered two dead men Friday near Quijotoa on the Tohono O'odham Nation, and the third body was found Saturday near Arivaca, according to a U.S. Customs and Border Protection news release.
In the incident near Quijotoa, which is near Casa Grande, the two men were suspected in marijuana smuggling. The bodies and three marijuana bundles were spotted by air patrols.
In the second incident, Border Patrol agents found the man's body about 100 yards from Arivaca Road.
Agents found out about the man after his sister was captured, and she told agents her brother had fallen and was unresponsive before he was abandoned by a group of border crossers.
In the past nine months, Border Patrol agents have reported close to 100 deaths throughout Southern Arizona.
As triple-digit temperatures continue, risks in crossing the Sonoran Desert cannot be overstated, officials said.
