PICTURED: Delaware couple shot and killed while visiting son's grave

This is most interesting how the parents were completely dedicated to their son that passed away in 2017. They showed a higher level of commitment and love to each other and their son, that has become rare in these modern times.

The twin sons revealed their mother and father were at the cemetery that morning as part of their daily 'ritual' of visiting their brother Anthony's grave.
Anthony, the couple's youngest son, was born with cerebral palsy and died from complications in March 2017 at the age of 54.
Although Anthony did not serve in the military, cemetery rules allowed his father, a peacetime army veteran in the 1950s, to bury one minor child or child with disabilities at the site.
The parents had been visiting the burial plot every day ever since.
'It was like a regimen. Mom and Dad visited my brother's grave every single day, without fail, unless there was inclement weather. They usually went there in the morning.
