Early one Saturday morning last June, Hugues de la Plaza was found stabbed to death in his apartment in San Francisco.
At the time, police couldn't tell whether the 36-year-old sound engineer was killed by an intruder or somehow killed himself. Few people commit suicide by jabbing themselves repeatedly in the chest with a knife
, but de la Plaza's door was locked, there were no signs of a struggle, and a security camera mounted outside his apartment saw no one but de la Plaza go through his front door.
His family and friends say police soon told them they were leaning toward concluding it was suicide. They said investigators speculated that de la Plaza, a dual French and U.S. citizen, had taken drugs that night while at a nightclub, came home and stabbed himself three times with a steak knife.
No bloody knife was found, but the investigators said de la Plaza could have washed one in the sink after fatally wounding himself.
To his friends and family, it was an absurd theory. De la Plaza was a social animal who loved life and had just gotten a new position at the educational software company LeapFrog. He had been making plans both for the next day and for several months down the line. Besides, they said, he turned away at the mere sight of blood.
Then an autopsy found no drugs in de la Plaza's blood and only a modest amount of alcohol
. Tests showed no traces of blood on the knife
found in the sink. Still, his acquaintances complain, police haven't officially labeled the death a homicide.
Homicide investigators won't talk about de la Plaza's death, referring questions to Gittens, who noted that the case is still open and that police have reached no conclusions.
Police know this much: When de la Plaza was killed, he had just returned to his Linden Street apartment in Hayes Valley from a Friday night with friends at the Underground SF nightclub.
Neil Zarama, a co-worker at LeapFrog, said de la Plaza had gone out on a date after work that day and had met up with friends at the club about 10:30 p.m.
At closing time, de la Plaza told Zarama that he was hoping to get together later with a woman he had met. Zarama said he later learned that the plan had fallen through.
De la Plaza walked the three-quarters of a mile from the club to his home. A surveillance camera mounted on the front of the building showed him going inside alone at 2:06 a.m. But there was a side entrance as well that was not covered by a camera.
De la Plaza went on his computer and used it until about 2:38 a.m., when police believe he was either stabbed or stabbed himself.
Wounded, he went outside his apartment, leaving blood on the doorknob and on the landing rail, then went back inside and locked the door, according to police.
A next-door neighbor reported hearing a commotion but no screaming. The neighbor, Orion Denley, a concierge at a local hotel, said a loud thud had shaken his wall as he was dozing off.
Police were summoned at 8:30 a.m. Saturday after a neighbor saw blood on the stoop. Officers had to break down de la Plaza's locked door.
Once inside, they found no knife by de la Plaza's side. In fact, while they found plenty of blood, they found no bloody knife. But they saw something they thought might be a remnant of blood on a knife in the sink.
Their theory was that de la Plaza had washed the knife after stabbing himself, but tests on the blade showed no trace of blood.
There was no suicide note. On a notepad, however, someone had written two sentences: "Learn as if you were to live forever," and, "Live as if you were to die tomorrow."
There were no intruder footprints, and the pattern of blood in the apartment did not indicate there had been a struggle, police said.
The autopsy showed that de la Plaza had been stabbed three times, including once in the neck. The report found no drugs in de la Plaza's blood, only alcohol at a concentration of 0.11 percent, a bit above the legal definition for drunken drivers, 0.08 percent.
The medical examiner's report said that de la Plaza's injuries were "not inconsistent with self-inflicted stab wounds," but that it was impossible to rule out homicide.
De la Plaza's friends, however, say police didn't do all they could to make that determination.
Jean-Phillipe Goudet, a French police detective who works in the United States and is based in Los Angeles, was brought in to assist San Francisco police after de la Plaza's family in France went to their government for help.
Nix said Goudet took some basic investigatory actions that police had failed to perform
, such as looking at what de la Plaza was doing on his computer before someone yanked the cord at 2:38 a.m.
"If not for Goudet, Hugues' laptop would still sit untouched," Nix said in her complaint to the city. "Homicide told Goudet they could not break into it. ... Four months after the murder, Goudet received permission from SFPD to bring two (computer) professionals - on the French government's dime - to break into the drive."
Nix said she hopes the laptop will provide clues as to whom de la Plaza had been meeting through online dating sites where he was active.
Goudet also was the first investigator to check de la Plaza's cell phone to determine whether he had sent or received calls or text messages that might help explain how he died, Nix said.
Police still have not performed DNA tests on the blood found at the apartment to determine whether any came from someone other than de la Plaza, his friends say.
Goudet would not discuss details of the investigation. He did not fault the police.
