Local policemen found Mlinar hanged in a wood-shed by his house in Benkovac at about 01.20 am Tuesday.
An autopsy was carried out at the Zadar hospital and no traces of violent death were found.
Mlinar recently came into the limelight after reporting an assault against him. He told the police that two young men had attacked him and tried to incite a dog to rape him. However, a medical examination revealed no evidence of physical or sexual abuse.
According to the police, Mlinar appeared to be suicidal and the police twice called urgent medical services to help him.
