A Lafayette man pleaded guilty and was sentenced to 80 years hard labor after killing two people, according to the district attorney's office. Joseph Delahoussaye was accused of killing Bobby "BJ" Duplechin and Rachael Alexander. Delahoussaye pleaded guilty Wednesday in front of 15th Judicial District Court Judge Valerie Gotch Garrett to two counts of manslaughter and one count of armed robbery in Duplechin's death. Lafayette Parish Sheriff's deputies responded to a reported suicide on Sept. 2, 2016, but later determined Alexander's death was a homicide and charged Delahoussaye. In exchange for his plea, Delahoussaye will serve 40 years of hard labor consecutively for each count of manslaughter. Additionally, he will serve 80 years of hard labor for the armed robbery, which will run concurrently with the manslaughter charges.
