Investigators say Matthew Wong and his wife had been separated for several months in February 2012 when he drove to her apartment complex in a rental car and waited for her to leave for work. Authorities say Wong chased his wife and tried to splash gasoline on her. Instead, he got the gas all over himself. The woman escaped into an apartment, and he poured gas on the entryway. When he lit it, fire blew back and engulfed him.
