Two suspects are on the loose after a home invasion-style shooting in Chattanooga overnight. Police found Christopher L. Sanford shot in the thigh on Navajo Road around 1 a.m. Police say two suspects armed with guns kicked in the door and demanded money from the people in the house. Sanford told detectives he walked in on the robbery in progress, not knowing what was happening, and confronted and struggled with one of the suspects. Sanford has been treated and released from a local hospital..
