HPD said 1.2 million pieces of evidence are currently stored but are no longer relevant.

Previously, evidence from long-ago cases, such as sticks, tennis rackets, bicycles and even rocks, was sometimes kept for decades.

They also said it allowed rats and mold to accumulate in evidence cabinets, risking contamination of new evidence.
