US Center for SafeSport have closed their investigation into the late figure skater John Coughlin, it has been confirmed.
Coughlin, a two-time United States pairs figure skating champion, was found dead by police last month.
Police confirmed his death had been a suicide.
Coughlin’s death came a day after he was placed under an interim suspension by the US Center for SafeSport.
US Figure Skating then issued a temporary suspension against Coughlin, pending a final resolution from the Center.
According to USA Today, Coughlin’s eligibility to participate in his sport had restricted by the US Center for SafeSport in December following a matter presented to the body.
USA Today reported that three people had accused Coughlin of sexual misconduct and that two of the accusers were minors at the time of the alleged incidents.
Coughlin claimed the allegations against him were unfounded.
US Center for SafeSport have confirmed their investigation has now concluded.
"Since the Center’s response and resolution process works to protect the sport community and other covered persons from the risks associated with sexual misconduct and abuse," a SafeSport statement read.
"It cannot advance an investigation when no potential threat exists."
The decision to close the investigation has disappointed US Figure Skating, whose executive director David Raith had previously called for it to continue.
Raith had asserted it would provide "clarity and closure", despite Coughlin no longer being able to respond to the allegations against him.
US Figure Skating admitted they were disappointed the investigation has now been closed.
"US Figure Skating is disappointed to learn of the US Center for SafeSport’s decision to close the investigation into the allegations against the late John Coughlin," a statement read.
"The allegations and Coughlin's death have left his family, those who reported the allegations, many in the figure skating community and survivors of abuse searching for answers."
The US Center for SafeSport do not typically disclose the nature of allegations.
The aim of the organisation, which launched in 2017, is to end all forms of abuse in sport.
They claim this includes bullying, harassment, hazing, physical abuse, emotional abuse, and sexual misconduct and abuse.
