Following the merger Seibel joined the staff of the Springfield Union as a sports writer and general news reporter, publishing accounts for that paper as well as the T-T for nearly 17 years before his departure for the Taxpayers' Association.

He was a prominent member of the "Holyoke Fourth Estate", a reporters fraternity, and in his own interest wrote a length history of the athletic notables of the city at a school, college, and professional level.

It was reported that leading up to his murder, Noel's had been from multiple people, including at least one who spoke broken French, and at least one specifically blaming him for a recent shake-up in the police force.

[15] With the case remaining unsolved, by November 11, 1954, a rift had apparently arisen between Seibel and Chief Potvin, who had been the youngest appointed to the post when he had been installed on June 8 of the previous year.

[19] Neither Seibel nor Potvin met their would-be assailant, and ongoing efforts by Holyoke Police across state lines through at least the 1970s turned up no new leads; to date Noel's murder, and the threats that followed, remains an open case.

[20][21] Two years after Seibel's death, the Holyoke Housing Authority dedicated a 40-unit complex of studio apartments in his name on the corner of Nonotuck and Hampden streets at the edge of the Highlands.
