The Honolulu Police Department is mourning the death of one of its own.  Thirty-nine-year-old Jens Magelssen accidentally killed himself at his Wilhelmina Rise home over the weekend. The police officer was hosting a barbecue for friends from the mainland on Saturday. He reportedly was showing his gun to them and thought it was unloaded. The Honolulu Star-Advertiser reports that Magelssen was taken to the Queen's Medical Center and he died Monday, after being taken off life support. Magelssen was on the police force for six years. Fellow officers describe him as a nice, quiet man and a good police officer who never got into trouble. The case is being investigated as an unattended death.
