David Del Rio's wife, Katherine Del Rio, offered a rare glimpse at them celebrating their daughter's first birthday amid his Matlock sexual assault investigation being reopened. "Yesterday we celebrated Coco Lorén Del Rio's 1st birthday. To say we are obsessed is an understatement," Katherine wrote via Instagram Story on Wednesday, January 21. "The joy she brings this family is unmatched." She continued: "I am profoundly blessed to be her mom. Nothing makes me happier." The social media post included photos from the celebration - with one showing David, 38, with his and Katherine's daughters.
