As a comic book expert with a deep understanding of the Spider-Man lore, I can provide you with an accurate account of how Peter Parker's parents, Richard and Mary Parker, met their end in the comics.

In the original comic book storyline, Peter Parker's parents are depicted as being CIA agents. Richard Parker is a scientist who worked on a top-secret project, and Mary Parker was his wife and a skilled operative. Their work in intelligence made them a target for various enemies, and they were forced to go into hiding to protect their young son, Peter.

The exact details of their deaths are not explicitly laid out in the comics, but it is heavily implied that they were killed as a result of their work with the CIA and the dangers that came with it. Their deaths are a source of mystery and are often referenced as a driving force behind Peter's actions and his commitment to fighting crime as Spider-Man.
