The Trail Went Cold – Episode 376 – Monika Rizzo

June 5, 1997. San Antonio, Texas. Police receive an anonymous phone call from a man who claims that 44-year old Monika Rizzo has been murdered by her husband, Leonard Rizzo, and that her remains can be found in her backyard. While a search of the property turns up nothing, investigators learn that Monika has not been seen for weeks and there are allegations of abuse in her marriage. One month later, a new search of the Rizzos’ backyard turn up over 200 bone fragments and it is eventually determined that they belong to Monika. While Leonard is suspected of having killed Monika, the authorities do not believe there is enough evidence to file murder charges and there are a number of unanswered questions about how she died. On this week’s episode of “The Trail Went Cold”, we explore a gruesome murder which has gone unsolved for nearly 27 years.

If you have any information about this case, please contact the San Antonio Police Department at (210) 207-7273.
