Andrew Kissel, 46, was found tied up and stabbed to death in his Greenwich mansion just days before he was to plead guilty in a multimillion-dollar fraud case.
Carlos Trujillo, who was Kissel's driver, and his cousin, Leonard Trujillo, have been arrested in connection with the developer's death, Greenwich Police Chief David Ridberg said Saturday.
"There is still a lot of information to be gathered and facts to be discerned," Ridberg said in a written statement announcing the arrests.
The arrest warrants are sealed. The chief said more information would be released Monday.
Leonard Trujillo, 21, is charged with murder and conspiracy to commit murder, police said. Carlos Trujillo, 47, is charged with conspiracy to commit murder.
Attorney Lindy Urso, who represented Carlos Trujillo shortly after Kissel's death could not be reached late Saturday. Information was not immediately available on whether Leonard Trujillo had an attorney.
