An altercation reportedly broke out last night involving two individuals, which authorities believe resulted in the tragic death of 53-year-old grandmother Melonie McKay outside her Reservoir residence.

Her family is grappling with the devastating news.

“I’m at a loss for words and unsure of my emotions,” her son Trent Ottrey shared with 9News.

“I shared a tearful moment with my younger sister,” he added.

According to McKay’s sister, the sorrow is almost unbearable.

“The mix of grief, anger, and confusion we’re experiencing is truly overpowering,” she expressed in a statement.

“Trying to understand why something like this happened, and how someone we lived near could commit such an act, only adds to the pain.”

A 44-year-old man was arrested at the scene and has been charged with one count of murder.

It is believed one of the children was in the car when it allegedly struck McKay.
