Authorities are trying to determine a motive for why a Noblesville man was shot Thursday while delivering medical supplies to a home in the community of Center in eastern Howard County. Joshua David Glyn, 22, who worked for a medical company, was hit multiple times in the torso, and taken to Howard Regional Hospital in Kokomo and then transferred to Methodist Hospital in Indianapolis in critical condition. Taken into custody was 61-year-old Charles E. Miller, who lived at the address. Officers saw several long guns, handguns and ammunition in the home. Authorities believe at least four nearby homes were struck by gunfire. It appears that shots were fired from multiple locations inside Miller's residence.
