Pima County Sheriff's Office is investigating two separate shooting and robbery incidents they believe were done by "rip crews."
Deputies said a 42-year-old man was shot after he and two of his friends were confronted by three suspects about seven miles west of the Red Rock housing community on Tuesday.
According to the victim, he and his two friends were from Hermosillo, Mexico and had crossed over the border illegally on foot about 10 days before.
They were walking on a trail when they were confronted by three armed suspects dressed in camouflage clothing and masks. The suspects spoke to them in Spanish and demanded their money.
After the victim gave them their money and said it was all they had, a suspect hit him in the face with a gun and shot him in the leg.
The victim told police the suspects ran to a nearby getaway vehicle. The victim's friends helped him to the side of a road before running into the desert to hide.
A resident driving by saw the victim and he was brought to a hospital and treated.
One of the victim's friends was found in the area and he and the victim were turned over to Border Patrol.
PCSO and Border Patrol searched for the suspects but none of them were found.
The second incident happened on Wednesday.
According to PCSO, a man was shot while trying to smuggle marijuana from Mexico to the U.S. with seven other men.
Deputies found a victim with a gunshot wound and another man near Interstate-8 near Smith Road with the help of the victim's GPS on his phone.
The man with the victim told deputies that he and the victim were part of a group of eight men carrying backpacks of marijuana from Mexico.
The group was confronted by five armed rip crew members who told them in Spanish to drop their backpacks, the man told deputies.
As the eight men tried to run away from the rip crew, at least one of the members started shooting at the men. The victim was shot in the buttocks.
While searching for the rip crew members, Border Patrol found two more members of the group of backpackers.
All three men were turned over to Border Patrol. None of the rip crew suspects were found.
