Rex Alan Necaise, Jr., lovingly known as "Moondog," passed away on July 12, 2026, in Gulfport, Mississippi, at the age of 53. Born on February 4, 1973, Rex was a lifelong resident of “Pistache” Pass Christian, Mississippi, and a proud graduate of Pass Christian High School.

Rex had a deep love for life and found his greatest joy on the water. Whether boating, fishing, or simply enjoying the Mississippi Gulf Coast, he was happiest surrounded by family, friends, and nature. He was also a devoted Rottweiler lover and never missed an opportunity to cheer on his beloved Dallas Cowboys. His easygoing personality, sense of humor, and love for those around him will be remembered by all who knew him.

He was preceded in death by his uncle Butch, aunt Linda Gay, and uncle Lonnie; (maternal grandparents) Everett and Betty Mae Cuevas; (paternal grandmother) Muriel Necaise.

Rex is survived by his parents, Rex and Gloria Necaise; his children, Nikki (Blake) White, Alanna (Ryan) Shaw, Joanie (Norman) Necaise, and Stetson Necaise; his paternal grandfather, Leamon Necaise Sr.; his brothers, Brad Necaise, Joey (Colleen) Necaise, and Josh (Krystle) Necaise; and his cherished grandchildren, Waylen Shaw, Josie Sipe, Brinnley White, and Sadie Sipe.

He is also survived by his nieces, Brailee (Mark), Amaris Necaise, Joslin Necaise, and Ashlinn Necaise, and his nephews, Dawson (Bella), Jaxton Necaise, and Braddex Necaise, along with many extended family members and friends who will forever treasure the memories they shared with him.

Rex's love for his family, his passion for the outdoors, and the laughter he brought to those around him will leave a lasting legacy. Though he will be deeply missed, his memory will continue to live on in the hearts of everyone who knew and loved him.

He will be greatly missed by his family.

In accordance with Rex's wishes, no services will be held at this time.
