Marylue Wigglesworth from New Jersey allegedly killed her husband David at their apartment on Christmas night.
Her brother has told DailyMail.com exclusively that: ‘They could argue about anything’.
Francis Gallagher, 58, said sister Marylue Wigglesworth, 51, and politically-active spouse David were very ‘off and on’ – despite the couple posting happy pictures of themselves on social media.
It was reported that police found David, 57, at their apartment in Mays Landing at 10.19pm Sunday night suffering from a gunshot wound. He died at the scene.
Marylue was arrested and charged with his murder. She is currently being held at the Atlantic County Justice Facility.
Gallagher of Mays Landing, also commented on Wigglesworth, saying: ‘Everyone in our family is in a state of shock.’
But asked if they were a happy couple, he replied: ‘So so. They were very on and off.
‘They could argue about anything. I have no idea what happened and I cannot comment over whether this was the result of political differences.’
The couple have a 25-year-old son, also David, who is an economist living in Philadelphia.
‘I haven’t seen Marylue since this happened,’ said Gallagher.
‘Nobody from our family has. I’ve tried to see her but I’ve been told we can’t until she has been up before a judge.
‘I support my sister, and my nephew David. However, I’ve been told not to say too much.’
The victim was found shot in a bedroom and a handgun was recovered nearby, according to The Press of Atlantic City.
David is remembered for his local efforts to elect GOP candidates to town positions, even running for office once himself on the Republican line.
The circumstances surrounding the fatal shooting remain unclear. David’s Facebook showed the couple happily spending years together, going on trips to Las Vegas, Philadelphia and Maryland and enjoying summers by the ocean.
Photos posted to David’s Facebook showed him and Marylue smiling as they took various trips together across the country and overseas.
In September, David posted photos from a trip to Maryland, and in November, Marylue posted photos from the Macy’s Thanksgiving Day parade in New York City.
Together, they have an adult son, Dave, who is an economist.
David is remembered for his community service and political activism, even serving as the best man for the current Mayor of Hamilton Township.
Marylue will appear for a detention hearing on Wednesday, the media outlet reported.
