In addition Hans Peterson was going through a nasty divorce which added to it. Traversa therapeutics is the name of the Biotech company that went broke and had raised over $10 million in funding. The intellectual property for Traversa was licensed to Solstice Biologics in San Diego and Steven Dowdy, one of the men shot is the owner of that company.
The ex-wife of Hans Peterson said he had been terrorizing her and also blamed the Cancer biologist for firing him and ruining the company. Neither victim was killed though and Steven Dowdy is a UCSD School of Medicine Professor. The company they were both working with and owned was developing a treatment for cancer. Sanofi-aventis entered into a contract with Traversa in 2010, so the company was not that old.
