The City of Maricopa Police Department says a suspect was found dead after firing at officers overnight, KGUN9 sister station KNXV reports.
The call started Monday night as a domestic violence situation in the El Dorado Lakes neighborhood.
A man at the home armed with an AR-15 reportedly exchanged shots with responding police officers before going back inside the home. Police say family inside the home was able to escape unharmed.
A SWAT team joined officers and used a robot to go inside, which later found the suspect dead in an upstairs closet.
Maricopa Police later confirmed the suspect's identity as Border Patrol agent Jeremy Russo.
It's not clear if Russo died from injuries sustained while exchanging gunfire with police or if he took his own life.
