Background
Tony Nenonen had a troubled youth, spending some time in juvenile detention before becoming a police officer. He developed a strong moral compass and detested police corruption. He partnered Detective Joseph Thorne for nine months before his death.
He appeared in Hellraiser: Inferno and was played by Nicholas Turturro.
His surname is a palindrome, a concept he initially struggled with.
Demise
Nenonen was helping Joseph Thorne hunt down The Engineer, a mysterious figure linked to multiple murders, when he and Thorne became separated. Somehow Nenonen was tied to a chair and killed while Thorne watched via telescope.
