The former Growing Pains star was last seen on 14 February (10). He disappeared during a trip to Vancouver and was reported missing by a friend after failing to show up for his flight home to Los Angeles on 16 February (10).
His parents, former Star Trek actor Walter Koenig and his wife Judy, issued an emotional plea to the 41 year old during a police press conference on Wednesday (24Feb10), when they begged Andrew to get in touch just to assure them he is "OK".
The same day, his friend Jenny Magenta confessed her fears that the star may have "taken his own life" - and now his family and friends have had their worst fears confirmed.
The tragic actor's body was found in Vancouver's Stanley Park around 12pm local time on Thursday afternoon (25Feb10).
Vancouver authorities held a press conference at 5pm (PST), just hours after the discovery, during which a police spokesperson revealed they had no reason to believe foul play was involved in Koenig's death. However, their investigations are continuing.
The representative told the news conference, "Andrew's body was found in the park by friends who had initiated their own search. Our investigations are continuing... We will not release any further details about cause of death. We have no reason to believe foul play was involved."
Koenig's dad Walter fought back tears as he told reporters, "We've already said what a great guy he was and a good human being... He was obviously in a lot of pain... What you can learn from this is that there are people out there who really, really care."
Judy Koenig added, "He was much loved and he had much to contribute in this world. This is the only statement that we are making. Please respect our privacy."
