UPDATE: At 4:43 p.m. Fort Worth police took a man into custody at a house in the 6800 block of Permian Lane.
Officers could be heard on a police scanner channel saying that the man had been shot in the face “of his own doing.”
Earlier scanner traffic indicated that there had been gunfire.
Police at the scene declined to identify the suspect, but early police reports indicated the man was a suspect in the slaying Monday of Re/Max realtor Suzanne Parsons of Haslet.

A MedStar spokesman said ambulances were standing by in the 6800 block of Permian Lane, but no one had yet been transported.
Scanner traffic also indicated that some gas had been deployed and officers were thinking about shutting off the water out of concern that the suspect might wash the smoke residue off.
At 3 p.m., scanner radio traffic indicated that the man had stopped communicating on an open line, but earlier police said they could hear him breathing.
Several minutes later, as the SWAT members prepared to deploy a robot to a second floor of the house to release more gas, officers said the man had resumed talking to them.
Earlier Tuesday afternoon, officers went door to door to evacuate neighbors.
Police descended on the neighborhood shortly after 11 a.m.
An intial police report indicated that a woman at the Permian Lane home called police to report that she found the suspect in her home about 11:30 p.m. Monday. The woman had met the suspect several months ago when he helped her move, according to the report.
The suspect told the woman that “I think I killed Susan,” according to initial police reports.
Parsons had an ex-husband by that name, according to Tarrant County court documents.
Parsons, 49, was found unconscious at the RE/MAX Heritage office, 4200 Heritage Trace Parkway, on Monday afternoon. She was pronounced dead at 4:38 p.m. Monday, but a cause of death was still pending.
Police got a 911 call at 4:19 p.m. Monday about a “cutting” at the real estate office, said Cpl. Tracey Knight, a police spokeswoman on Monday.
Knight said the woman was employed at the office, and she indicated that officers were looking for a specific person.
“I can say it’s not a stranger-on-stranger crime,” she told reporters at the crime scene Monday evening.
According to a RE/MAX website, Parsons was a realtor at the Heritage office. She was licensed as a realtor in 2005. She joined RE/MAX in 2010.
The couple’s divorce was finalized on Dec. 16, according to court papers.
