After he didn’t show up to work Monday, a concerned co-worker went to the Lower Haight apartment of Philip DiMartino around 1 p.m. and spotted his body through a window, lying dead on the floor, officials said.
The 36-year-old marketing manager was reportedly riddled with stab wounds in his 138 Hermann St. dwelling, a death that has baffled police since no witnesses have yet come forward with any information.
DiMartino may have died sometime over the weekend, police said. A homicide is suspected, though a cause of death has not been confirmed.
“It’s just very weird all around,” police Officer Albie Esparza said.
DiMartino was a senior marketing manager at Archstone, a national operator of apartment complexes that runs a building in the South of Market area, a company official confirmed. He worked with the company since 2002, according to social networking sites he held.
Archstone describes itself as an “owner, operator and developer of apartment communities.”
The company said it was “shocked and saddened” by the death, describing DiMartino as “more than an incredibly talented professional.”
“He was a friend, and a member of the Archstone family,” spokesman Peter Jakel said. “Our thoughts and prayers go out to his friends and family.”
The case is reminiscent of an internationally famous mystery in which a 36-year-old man with dual French and American citizenship was found dead with three stab wounds inside his locked apartment in June 2007.
Hugues de la Plaza was found stabbed to death in his Hayes Valley apartment. For nearly two years, San Francisco investigators told the family that their son likely killed himself, according to his father Francois de la Plaza. French investigators recently released a report determining the death was a homicide.
The case gained more exposure last year when it appeared on the "true crime" TV show "48 Hours Mystery."
