Dogs sniff out wrong suspect; scent lineups questioned
By Ed Lavandera
VICTORIA, Texas (CNN) -- The interrogation room inside the Victoria County Sheriff's Office is sterile and cold. There's a table in the middle, a one-way mirror and a hidden video camera that lets investigators watch suspects.
Michael Buchanek knows the room well. He was part of countless investigations. Buchanek spent more than 25 years with the Sheriff's Office as a commander of operations.
But on March 16, 2006, Buchanek found himself sitting in the interrogation room. This time, he was on the other side of the table. The day before, his neighbor and friend, Sally Blackwell, was found strangled to death with a rope. Her body was left in a field five miles from her home.
Buchanek sat in the interrogation room with three homicide investigators, former brothers on the force. But the investigators were no longer friends. Buchanek was now the prime suspect in Blackwell's murder.
