Cesar Luna De Leon was 35 years old when he was killed in St. Louis on Sunday, June 27, 2010. The St. Louis Metropolitan Police Department investigated his death, and the Washington Post's homicide database, which tracked killings in St. Louis through 2017, lists it as a homicide that remained open with no arrest.
Beyond his name, his age and the date of his death, almost nothing about Cesar Luna De Leon has been made public. No news story about the killing, obituary, memorial page or family fundraiser could be found for this account. He surely had family, friends and neighbors who remember who he was, but none of that has entered the public record.
Because so little has been released, even the basic circumstances remain unknown to the public. The record does not say how he was killed, whether he was attacked indoors or on the street, whether he knew his attacker, what time of day it happened, or whether he died at the scene or later at a hospital.
It does not say whether investigators ever identified a suspect.
Cesar Luna De Leon is also listed on CrimeTea, an online database of unsolved cases, where his death is recorded as an active murder case in St. Louis. The entry repeats the basic record but adds no details about what happened, which suggests that little beyond the police record has ever surfaced.
Cesar Luna De Leon's name also appears in a 2018 Washington Post investigation that listed thousands of homicide victims across major American cities whose killings had not led to an arrest. Being on that list means that, years after the killing, the case was still counted among those for which no one had been arrested.
His background also stands out. He was 35 and recorded as Hispanic, while the great majority of homicide victims in St. Louis in those years were Black. His compound surname suggests family roots in Mexico or Central America, but no record found says where he was from, how long he had lived in St. Louis, or whether he had relatives in the area. Searches find several living people of the same name in Mexico, none connected to this case.
The location recorded in the Post's database places his death in the northwestern edge of the city, near its border with St. Louis County, a residential area of modest homes and commercial streets. People who lived or worked in that area in June 2010 may remember the police activity that followed his death.
The killing came during a stretch when St. Louis consistently ranked among the most violent big cities in the country. The city recorded 143 homicides in 2009 and 144 in 2010, a very high toll for a city of about 320,000 residents, and a large share of those cases never led to an arrest. Homicide detectives carried heavy caseloads, and killings that drew little press attention were easily forgotten by the wider public.
No arrest, criminal charge or court case connected to the death of Cesar Luna De Leon could be found in news archives or public records. More than 16 years later, there is no public sign that anyone has been held responsible. Anyone who knew Cesar Luna De Leon and saw him in the days before he died, or who heard talk afterward of what happened, may be able to help. Even a small detail, such as a name overheard, a car seen leaving the area or a conversation remembered, can help detectives move a case forward. Anyone with information can call the St. Louis Metropolitan Police Department Homicide Division at 314-444-5371, or leave an anonymous tip with CrimeStoppers at 866-371-TIPS (866-371-8477).
