Denise Cochrane was an 11-year-old sixth grader from Brockton, Massachusetts, who disappeared on May 23, 1975, after leaving her home on Essex Street to walk to Huntington Elementary School. She was the youngest of four siblings.

On April 28, 1976, Denise’s remains were found at the Brockton Iron and Steel Company inside a transformer casing. Investigators concluded she had suffered fatal injuries, including a skull fracture, and that her body had been moved into the casing after apparently falling from a crane. Despite extensive efforts, no one has ever been charged in connection with her death and the case remains unsolved.

Denise’s family and the Brockton community continue to live with unanswered questions about who harmed her and why. If anyone knew Denise, saw her on May 23, 1975, or has information about activity at the Brockton Iron and Steel Company that spring, please come forward.
