A body was found inside a home after firefighters extinguished a fire in a neighborhood in Celina Wednesday, city officials say.
According to a city official, construction workers building homes in the area reported hearing something that sounded like gunshots and seeing smoke coming from a house in the 1400 block of Anvil Court at about 11 a.m.
A construction worker told NBC 5 he heard several shots, saw smoke then witnessed a man running away from the scene.
Once the fire was out, firefighters found a body inside the home and notified police. The victim's identity has not been released.

Mayor Sean Terry confirmed a man is now in custody, but didn't reveal any information about his identity or how he was developed as a suspect.
Terry said the description of the suspect given by construction workers helped lead to the arrest.
"We know this was an isolated incident based off the information we have and the people we interviewed, so our citizens of Celina and Prosper can know that we got the guy," Terry said.
Neighbors say the people who live at the home moved in in September.
Police are asking nearby homeowners with surveillance systems to check them for video they may have recorded relating to the incident.
The homicide is the first in Celina since 1985, Terry said.
While they have detained someone in the investigation, he did not know if that person set fire to the home or if the incident is connected to shootings Tuesday in Prosper and Frisco.
Police said they expect to release additional information on Thursday.
Investigators are asking those who live in the area to check home surveillance cameras for any unusual footage from late Wednesday morning.
Celina ISD schools were on lockdown Wednesday afternoon during the initial response.
