Soh, 22, was enrolled as a senior at the university when a jogger discovered his body outside the Dorchester high-rise apartments on the morning of Oct. 26, 2013. Police said that there were no signs of foul play and that it appeared as if Soh had fallen to his death.

Soh’s family has since rejected that explanation, citing a number of different reasons. The family spells out their case in a confidential 30-page settlement proposal sent to Washington University. The Post-Dispatch has obtained a copy.

The family explains that Soh had a bright future but fell in with a freewheeling drug culture at Washington University that ultimately led to his death.

As one child in a set of triplets, Soh was the only one of his siblings to show interest in joining the family business.

The Soh family operates a chain of Papa John’s restaurants in South Korea.

The family’s St. Louis attorney, Albert Watkins, said the Soh family enjoyed what’s akin to royalty status in South Korea.
