48 Hours S36E12 - The Journals of Maria Muñoz

In the early morning of Sept. 22, 2020, police officer Gregorio De La Cruz responded to a call at a home in Laredo, Texas. At the top of the stairs of the house, Joel Pellot, dressed in surgical scrubs, was performing CPR on his wife, Maria Muñoz. Paramedics and police jumped in to help, but at 3:58 AM, less than three hours after Joel Pellot had called 9-1-1, 31-year-old Maria Muñoz was declared dead inside their home. Was Maria's death a suicide, an accident or a murder? Authorities turned to her journals for help.
