Papa's still missing, but thank you all who've written me. Mama has spent some time looking for him on her own early in the morning today. Then she took his picture to the police station at Moskovskaya St., only to discover that they were planning to begin working on his case tomorrow. "It's not some hooligan that's missing," she told them. "It's a person who is ill, and it's been 12 hours already." She also asked them quite decidedly whether they needed a kick in the ass from someone way up high to get them to do their job. That and some real intense crying seems to have helped, and now a young and rather attractive woman (on really high platform heels) from that police station is calling places and walking around with mama. She's contacted all the usual medical places, but they don't have anyone who'd fit his description. I'm staying home with Marta - because we still have a tiny hope that he may find his way back by himself. Again, thank you for you help, prayers and positive thoughts.
Here's papa's photo, taken in April this year, on the day Marta and I were going back to Moscow:
A larger copy is here, and the really huge original - here.
Yesterday, he was wearing jeans and a blue polo shirt.
