There are confirmed cases of anacondas and rock pythons swallowing humans. There are unconfirmed reports for Burmese and Retics also. There has not been a confirmed case of a captive constrictor swallowing anyone. In the 1960’s a large Retic in a side show did kill it’s handler and attempted to swallow him, but he did not get past the head. The most recent account I know of complete human consumption involved a Rock and a Shepard. Two boys were watching over sheep, the snake attacked one and the other ran for help. By the time help arrived the snake had swallowed the boy. The men stoned the snake and he regurgitated the boy’s body. Now that is not to say that large constrictors do not kill their owners. According to Reptiles Magazine, Burms are killing two people a year in the United States.
