"Vanderpump Rules" star Scheana Shay is turning to fans for help after her cousin Phillip Tate went missing from a retirement community on Tuesday. The reality starlet took to her Instagram, pleading with anyone who has information on his whereabouts to reach out to her or her mother, Erika van Olphen, who is Tate's first cousin. The 67-year-old was last seen with his wife visiting his mother-in-law at Westmont Village Facility in Riverside, CA three days ago. Security footage shows him leaving the parking lot by himself on foot. Adding even more urgency to the situation, Scheana Shay's team tells The Blast that Tate has dementia and diabetes.
