Brazilian soap star RODRIGO HILBERT and his model/actress girlfriend FERNANDA LIMA tried in vain to save a German-born wine mogul who was killed in a hit-and-run boat accident on New Year's Eve (31Dec08).
Christian Wolffer - who owns New York's Wolffer Estate Vineyard - was struck as he swam off the coast of Paraty, Brazil on 31 December (08).
Hilbert, 24, and Lima, 33, saw Wolffer pleading for help, and dashed into the sea in a kayak to rescue him. They dragged him back to shore, but failed to revive him.
Cops are now investigating Wolffer's death, at the age of 70, as a murder.
A police spokesperson tells the New York Post, "It is a homicide and is being investigated as such."
Hilbert and Lima have a released a statement that reads, "We are saddened and shocked. It was a brutality. We did what we could."
