Mostly yes, but treat the “kid with a frying pan for a shield” bit as a medieval chronicler’s flourish, not courtroom-grade fact. The core claim—that Richard was shot by a young defender, often identified as Pierre Basile/Jean Sabroz/Bertrand de Gourdon—shows up in later accounts, and one version says he faced Richard with a crossbow in one hand and a frying pan in the other as makeshift protection; Wikipedia’s summary of the tradition reflects that, and History Hit notes the killer’s identity is disputed. So: the “young shooter” part is plausible, the “pan as shield” part is famous but shaky. InLeo doesn’t seem to have anything useful on this exact bit, so the history sources carry this one.
