Mantwell James

Mantwell James was 25 years old when he was stabbed to death on Tuesday, Feb. 28, 2012, in Lancaster, in the Antelope Valley of northern Los Angeles County. According to the Los Angeles County Medical Examiner-Coroner, he died of stab wounds after an attack in the 44200 block of Cedar Avenue. His death was ruled a homicide, and it is listed as a Los Angeles County Sheriff's Department Homicide Bureau case.

The coroner's records describe him as a Black man. The Los Angeles Times Homicide Report gave a brief account based on information from sheriff's homicide Det. House, who was handling the case. Mantwell was stabbed during a fight, House said. After the incident, authorities were called, and he was taken to Antelope Valley Hospital, where he was pronounced dead.

House told the Times that the killing was not gang-related, and that no one had been arrested. "Because the investigation is ongoing, House declined to provide additional details about the case," the Times reported. The account does not say who was involved in the fight, how many people took part, what it was about, or whether Mantwell knew the person who stabbed him. It does not say what time of day it happened or whether anyone else was hurt.

The fact that detectives could say the killing was not gang-related suggests that they had learned something about the people involved or the reason for the fight. That information has never been made public, and no later report has said whether a suspect was ever identified.

Beyond these details, almost nothing about Mantwell's life has been made public. No obituary, memorial page or family fundraiser could be found for this story, and no news outlet appears to have followed up on the case. His first name is unusual, which makes it all the more striking that so little about him can be found. 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 whether the fight happened inside a home or on the street, whether it began as an argument, or whether anyone tried to stop it.

Lancaster is the largest city in the Antelope Valley, in the high desert north of the San Gabriel Mountains, about 70 miles north of downtown Los Angeles. Its neighborhoods range from older streets near the city center to newer housing tracts spread across the desert floor. Lancaster contracts with the Sheriff's Department for police services.

Hundreds of people are killed in Los Angeles County every year, and a large share of those killings end without an arrest.

No arrest, criminal charge or court case connected to the death of Mantwell James could be found in news archives or public records. More than 13 years later, there is no public sign that anyone has been held responsible. Anyone who saw or heard about a fight on Cedar Avenue on Feb. 28, 2012, or who knew Mantwell and the people around him at that time, may hold information that could help detectives. Even a small detail, such as a name overheard, a vehicle seen nearby or a conversation remembered, can help detectives move a case forward.
