NEWARK, N.J. - The former manager of late boxing champion Arturo Gatti of Montreal says new evidence will show his 2009 death wasn't a suicide.

Pat Lynch says the results of a 10-month private investigation will be released at the end of August.

Gatti was found in July 2009 while he and his family vacationed in Brazil. The popular junior welterweight champion had retired from boxing two years earlier with a career record of 40 wins and nine losses.

Gatti's wife was arrested for his murder but later released. Police concluded Gatti hanged himself from a wooden staircase column in their rented apartment.

Lynch says he spoke to Gatti a week or before the Brazil trip and Gatti hadn't seemed depressed.

The Jersey Journal first reported the private investigation in its Tuesday editions.
