That led detectives to check at least four more surveillance cameras, all of which would capture the suspect on tape.
A camera at the 7-Eleven on 50th Street and MacCorkle Avenue showed a white man wearing blue jeans and a dark jacket. The man was seen approaching Molle's house, and walking away from the house about 30 minutes later, according to the complaint.
When the man approached the house, he wasn't carrying anything. When he left, he was allegedly carrying a white bag and a black garbage bag.
Detectives then got footage from cameras at Drug Emporium and the Computer Warehouse, both on MacCorkle Avenue. Both cameras showed the man walking east in a nearby alley, according to the complaint.
Molle's sister told police that she thought a tin can filled with change had been taken from her brother's home. That led police to the Kroger at 5717 MacCorkle Ave. S.E., which has a Coinstar machine that automatically rolls change.
Cameras at the Kroger also showed the suspect, who still had the white bag, but no longer had the black garbage bag, according to the complaint.
After retracing their steps and searching the alley, police found a trash bag with the bloody hammer and gloves in a Dumpster behind Drug Emporium.
Caldwell's girlfriend identified him from still images taken from surveillance cameras, according to the complaint. She allegedly told police that Caldwell lived with her -- about 20 blocks east of Molle's house -- and said that Caldwell was at a friend's house on Clemson Avenue in Rand.
Police found Caldwell there and arrested him.
Kanawha Magistrate Joe Shelton arraigned Caldwell and set a preliminary court date for Jan. 16. Caldwell was taken to South Central Regional Jail, where he was being held without bond.
