It's not clear if McKinsey's past was directly related to his death.

What prompted his in-laws to shoot him on this particular weekend afternoon has not been revealed.

The elderly in-laws were taken into custody shortly after the shooting. A woman named Tracy A. shared a photo of the elderly husband being handcuffed in the park.

Witnesses were shocked.

 There were kids and families, just like you see now,  said Kevin Stein of Dublin.  This parking lot is full on a Saturday. I mean this place is busy on a Saturday. It's incredible that they'd just do that right in front of everybody. 

The city of Dublin issued a statement about how  deeply saddened  they are, stating that  incidents like this are rare in our community. Dublin remains a safe place to live, work, and visit.
