Police didn’t believe the Sharon Tate murders had anything with the LaBianca murders either despite glaring similarities.
Sometimes cops are “target fixated” with early theories and exclude new evidence that goes against their preconceived ideas.
Cops believe the Tate murders were drug related and it took Susan Atkins blabbing to a cellmate to redirect them to a new direction.
Not positive this has the same effects but it could be.
In Nashville’s famous Marcia Trimble murder case the “experts” told the police that in this type of case the culprit is usually a neighborhood boy. The police overlooked the connection to a series of crimes close to Vanderbilt’s campus and kept harassing innocent neighborhood boys. DNA finally solved the case and the thug perp also raped and murdered my former classmate Sally DePrez, a sophomore at Vanderbilt. Jerome Barrett was convicted but is still breathing air in the prison system.
