The body of a man investigators said murdered his wife at an Orange County park has been located.

Orange County deputies said Julian Paris was found dead by family members from a self-inflected gunshot wound, next to his late son's grave at Woodlawn Cemetery.

Paris had been on the run since Wednesday, after investigators said he fatally shot his wife, Nicole, at Dr. Phillips Community Park.

Deputies said the suspect's family thought they might find Paris at the gravesite.

Paris' ex-wife and daughter found him dead at 7:20 p.m. Thursday. Paris' son died two years ago in a pedestrian accident at age 18.

Meanwhile, the couple's three surviving children witnessed the shooting Wednesday afternoon at Dr. Phillips Community Park. 

Deputies were called out to a domestic violence incident involving the recently separated couple, hours before Nicole was killed.

But right now, investigators don't know why he killed himself.

"You all know that he was going through a separation, but we do not know why he took this extreme drastic measure. We got the call around 7:25 (p.m.), family called saying they found the body of Mr. Paris at his son's grave," said Jane Watrel of the Orange County Sheriff's Office.

Paris had several aliases. His family said his given name is Rick Adderly.

It's also been confirmed that Paris had known his wife Nicole for more than 20 years, because he was her stepfather.

The two married in 1998, but before that, he was married to Nicole’s mother, who found his body Thursday night.

Deputies are still looking for his white Kia Spectra with Florida license K259IV.

The couple leaves behind three surviving children.
