Panera Bread’s highly caffeinated Charged Lemonade is now blamed for a second death, according to a lawsuit filed Monday.

Dennis Brown, of Fleming Island, Florida, drank three Charged Lemonades from a local Panera on Oct. 9 and then suffered a fatal cardiac arrest on his way home, the suit says.

Brown, 46, had an unspecified chromosomal deficiency disorder, a developmental delay and a mild intellectual disability. He lived independently, frequently stopping at Panera after his shifts at a supermarket, the legal complaint says. Because he had high blood pressure, he did not consume energy drinks, it adds.
