Francois de la Plaza came to San Francisco from France for the fourth time since his only child died, this time with a $100,000 reward for information in the death of his son, 36-year-old /*Hugues De La Plaza*/.
Francois no longer has confidence in San Francisco police, according to documentary filmmaker Marie-Anne Theriez, who has accompanied the de la Plaza's to San Francisco with a film crew and acted as a translator.
It shouldn't be his role to investigate; if the police had done its job, he wouldn't have to be here doing what he does," Theriez said.
Hugues was found dead in his San Francisco apartment in June 2007. The medical examiner said the cause of death was multiple stab wounds, but the manner of death remains undetermined.
A knife was found in the kitchen of the locked apartment, but there was no blood on it.
French police came to San Francisco and did their own investigation, ruling the death a murder.
But San Francisco police have yet to rule it a homicide, thinking he could have stabbed himself, and washed the blood off the knife, according to Francois.
"He says it's a very stupid way to see his death because there is no element at all that shows suicide," Francois said through Theirez.
Francois will formally offer the reward on Thursday.
