The Seattle Police Department has strongly denied reports claiming local law enforcement officials have re-opened the investigation into the death of Nirvana lead singer Kurt Cobain.

A representative for Seattle PD told Variety that an inhouse cold case detective simply went through Cobain’s file in anticipation of the upcoming 20th anniversary of the rocker’s death.

“He came upon some film that had not been developed, that’s it,” the rep said.

The photos, taken from four rolls of 35 mm film from the scene of the singer’s death, were developed just last month. Law enforcement officials told KIRO 7 that the images are better than the Polaroids used in the first investigation, almost 20 years ago, and Seattle PD will release one of the photos Thursday.

Cobain was found in his home on April 8, 1994, with a gunshot wound to the head. The Nirvana lead singer’s death was ruled a suicide. He had injected a lethal dose of heroin, according to the coroner’s report.

He also left a suicide note at his home.
