Family’s Heartfelt Plea
The Nasr family has shared a message hoping it will reach Allister:
“If you see this, please know how much we love and miss you. You have always been the heart of our family, bringing kindness, compassion, and joy to our lives. It breaks our hearts not to share everyday moments with you—meals, laughs, or even just a simple good morning.
Your grandparents, brothers, relatives, and friends are all praying for your safe return. If you’re not ready to reach out directly, please just let someone know you’re safe. Avi especially misses “huggy” and “tuck in.” No matter what, we are here, ready to welcome you back with open arms.”
Authorities believe Allister may still be in the St. Petersburg area, but he could also have traveled to Fort Myers or Kissimmee, Florida.
To increase awareness of Allister’s case, his missing poster is being featured on the Ring Neighbors app through a partnership between NCMEC and Ring. This will reach millions of users and provide real-time updates.
