A former Texas official and his wife were allegedly murdered inside their home by their troubled, gun-wielding son - who was then shot by responding police officers. 

Cops discovered the couple - Jackie Ragan, 72, and 73-year-old Leonard Frank Ragan - inside their tunning McKinney home on Sunday morning. 

Leonard Frank Ragan once served as the McKinney city manager. 

Officers were called to the property after concerned relatives requested a wellness check on the pair, as they had not heard from them for several days, the McKinney Police Department said. 

The responding officers entered the home through a back door - immediately finding Jackie and Leonard dead in the living room. 

As authorities continued to probe the scene, they discovered the victim's son, Bryce Ragan, 34, holding a firearm in a bedroom. 

The police officers then drew their own guns and shot Bryce multiple times in the bedroom after he allegedly did not comply with their demands to drop his weapon. 

He was then taken to the hospital, where he is said to be in stable condition. No officers were harmed in the gunfire.

While police have confirmed that Jackie and Leonard's deaths were homicides, they have not specified whether they were shot. 

The murders are under investigation and authorities said there is no threat to the public.

Bryce remains in the hospital, but has been charged with capital murder of multiple persons and three counts of aggravated assault of a public servant.  

Texas Rangers have also launched an investigation into the officer-involved shooting.  

Leonard served as the city's manager from March 2008 to June 2010.

'Our condolences and prayers are with the family. We are unable to comment further while this is an active investigation,' current city manager, Paul Grimes, told NBC 5. 

Jackie's heartbroken brother, David Foster, expressed his frustration and devastation in a Facebook statement about the tragedy. 

'What in the hell is wrong with the world today?' he wrote.  

'My nephew has murdered his parents, my only sibling, the sweetest and kindest sister I could have asked for, who never gave up on me, and her husband Frankie, the most honest man I have ever known.'
