Investigators say it now appears a man found dead in an office building where a software company founder also was shot was a homicide victim, not the suspected gunman.

Adams County sheriff's officials say 42-year-old Thomas Ciancio of Castle Rock and 58-year-old Rex Fowler were shot in the head Wednesday. County Coroner James Hibbard said Thursday that Ciancio died of multiple gunshot wounds to the head. Fowler is hospitalized.

Hibbard says it appears Ciancio's death was a homicide. Sheriff's spokeswoman Candi Baker says a suspect hasn't been named, but no one else is believed to be involved in the shootings. Investigators haven't said publicly what they think happened.

Fowler founded Fowler Software Design, where Ciancio was the former chief operating officer.
