The Alphabet Killer (2008)

A ten year old girl is found brutally murdered outside the small blue-collar city of Rochester, New York, and obsessed police detective Megan Paige (Eliza Dushku) suffers a mental breakdown while trying to solve the crime. But when the child-killings resume two years later, Megan’s return to the investigation also brings back her own horrific hallucinations. Even if she can prove a ‘double initial’ connection to the slayings, will she hang onto her sanity long enough to catch a psychopath? Based on the true story of the murders that shocked America.
