Inside the Maria Munoz murder case: A look at the evidence

Maria Muñoz , a young and healthy Texas mother, died unexpectedly. A toxicology report later revealed seven different surgical drugs were found in her system. Was it murder or a terrible accident? The evidence presented at Joel Pellot's trial for the murder of his wife tells a different story from what he told police happened the day Muñoz died.

Muñoz, 31,  a stay-at-home mother, lived in Laredo, Texas, with her two young sons and her husband, Pellot. On Sept. 22, 2020, Pellot called 911 saying Muñoz may have taken some prescription pills and was not breathing. First responders tried to save her but after failed attempts, Muñoz was declared dead at 3:58 a.m. that day. The first officer on the scene, Gregorio De La Cruz, told "48 Hours" that Pellot's behavior seemed suspicious and certain aspects about the scene didn't quite make sense.
