 Police in Oklahoma City say they've arrested a 70-year-old homeless man. In suspicion, he set fire to two people Tuesday morning. It appears the two victims, a man and a woman, were also unhoused and sleeping behind a building when they were sprayed with a flammable fluid and set on fire. The man expected to recover, though he's in danger of losing a limb. The woman remains in critical condition and we're told she may not survive.
