LOS ANGELES (Reuters) - Peter Falk, star of the 1970s hit TV drama Columbo, whose role as the rumpled detective of the same name earned him four Emmys, has died after years of battling Alzheimers disease. He was 83. Falk passed away peacefully at his Beverly Hills home on Wednesday evening, according to a statement issued by his wifes attorney. The actor enjoyed a long and successful career, first on the stage, then in movies and on television, where he gained fame as police lieutenant Columbo, whose seeming absent-mindedness was actually a ruse to cover for his shrewd questioning of suspects and investigations. He earned two nominations for the film industrys top honours, the Oscar, for supporting roles in 1960s Murder, Inc. and in Pocketful of Miracles the following year. Falk took hold of his first Emmy trophy in a leading role in a 1961 production of The Dick Powell Theater,.
