A homeless man who spent three days stuck in deep mud near the Rio Grande river in New Mexico was rescued after high school students on a field trip heard him yelling for help. Fire crews found the man stuck on a reed island and used a pulley system to bring him out of the mud and up a cliff, the AP reports. His freedom won't last long, however: Police discovered that the man is wanted on a felony warrant for aggravated assault and they plan to arrest him as soon is he is released from hospital, where he is being treated for hypothermia.
