The Lafourche Parish sheriff is searching for a Larose man who they say is a suspected drug dealer linked to two overdoses. According to the sheriff, Thursday morning a 15-year-old girl was found dead and a 16-year-old boy was hospitalized. Detectives took Blayne Terrebonne, 18, of Larose, into custody in connection with this incident. The sheriff believes Terrebonne gave the drugs to the teens. Around 4:30 a.m. deputies responded to a Galliano home after the teens were reported to have overdosed. Narcan was administered and the boy regained consciousness. Less than three hours later, deputies responded to a call at another Galliano residence where a 15-year-old girl was found dead. The cause of death is suspected to be a drug overdose, according to the sheriff. A warrant has been issued for Terrebonne's arrest. Detectives say they strongly caution anyone who has purchased illegal drugs from Terrebonne or any of his known associates that there is a great risk of overdose if those drugs are taken.Anyone who has purchased narcotics from him is asked to contact the Lafourche Parish Sheriff’s Office Criminal Investigations Division at 985-532-4320.
