BRENTWOOD - Police have charged a Brentwood mother with reckless endangerment for allegedly using a barbecue grill for heat, which they say led to carbon monoxide poisoning. The incident happened on Merrill Street around 4 a.m. Authorities say Marie Blaise pulled the grill into the house and lit it to create heat after running out of heating oil, but the home quickly filled up with poisonous gas. Blaise, her husband, Yves, and their three children all fell faint and rescuers rushed them to the Nassau University Medical Center with carbon monoxide poisoning.Yves Blaise says last night was a mistake, and that he doesn't think his wife should be charged in the case. Neighbor Frank Fortuna says he feels for the Blaises because it's tough coming up with money to pay heating bills, and sometimes people turn to unconventional methods to stay warm. Once Marie Blaise is released from the hospital, she is expected to appear before a judge.
