Urgent 🚨 question

Hello, we need help. Our Cat by Name "Chief" is missing. We originally bought him from a Breeder more than a year ago. We love him. We had to leave the country urgently due to my father having a stroke and so we asked the breeder who said she can take care of him for a month. Fast forward just 4 days, she texts me on Instagram that she cannot find the Cat and that Chief left the house and ran away. Now this cat for the whole year we had him was scared from even the noise coming from outside and would run to hide underneath the bed. Moreover she lives on 2nd floor and she says the cat jumped! Says cannot find him anywhere. We don't have a collar on him that says his name or contact information. What should we do. Please Please any help would be greatly appreciated Chief is a Golden white colored male british longhair cat, he has Green Eyes, weight approximately 10 lbs. His passport says his name is “Peepo”. Last seen on 6008 Ridgecrest Rd, Dallas 75231, apartment complex named "The Pearl at midtown".
