Deputies have identified the man found dead inside a Vista home on Wednesday.
The man was identified Thursday as 51-year-old Robert Pierro by the San Diego County Sheriff's Department (SDSO).
Just before 11 a.m., deputies from the Vista Sheriff's station received a report of an unresponsive man with trauma to his upper body inside a home on the 2200 block of San Clemente Avenue near Rancho Minerva Middle School.
According to SDSO Lt. Kenn Nelson, construction workers came back to the property and found Pierro unconscious inside. Despite first aid efforts, he remained unresponsive and the workers called the police.
Deputies arrived at the scene and found Pierro dead inside.
Neighbors told NBC 7 that Pierro ran a roofing and solar panel business out of the home. They said that he bought the home about three years ago and has been working on it ever since.
"It's calmed down in the last three months, but it was pretty chaotic for a while," neighbor Carrie Gamble said. "It's appalling to me to see this happen."
Nelson said the victim is connected to the home but at this time, it is not known if he is the homeowner.
"He put a fence up and he's got the gate there," neighbor Jim Morhman said. "I've had no contact [with Pierro] except for when he first moved in. I went up and said hi and that was about it."
Court documents show several civil lawsuits have been filed against Pierro's company, R.E. Pierro. Two of the lawsuits claim that Pierro owes the filing parties money.
Sheriff's Homicide Detail is conducting a homicide investigation.
The San Diego County Medical Examiner's Officer will conduct an autopsy to determine the cause of death.
