The body of a man was found northwest of Marana Friday afternoon.

The body was found at about 2 p.m. near the railroad tracks just off Interstate 10 near East Camino Adelante Road and East Park Link Drive in Red Rock, Tim Gaffney, spokesman for the Pinal County Sheriff's Office, said in an email.

"There were no obvious signs of external trauma and no clear indications of foul play," Gaffney said.

The investigation is ongoing.
