Lafayette Homicide: Christopher Jaber Identified as Victim

Contra Costa County Sheriff’s investigators are working a homicide case in Lafayette after a fatal stabbing Saturday morning left one man dead and a suspect behind bars on a $1 million bail hold.

Deputies responded to a home on Westminster Place around 11:30 a.m. following a report of a suspicious person inside the residence. They found a deceased male victim. By Saturday evening, sheriff’s officials announced they had detained and arrested a man seen walking in the area. That suspect is 35-year-old David Prince of Chico.

The victim has since been identified as 34-year-old Christopher Jaber of Lafayette. Neighbors told local television stations that the Westminster Place home was occupied by a couple, both physicians, along with an adult son in his 30s. Jaber appears to have been that son.

The killing marks the first homicide in the city of Lafayette since 2022. Lafayette, a wealthy Contra Costa County suburb tucked into the hills east of the Caldecott Tunnel, contracts with the sheriff’s office for police services rather than operating its own department.

What makes the case particularly disturbing is a Facebook post that has now surfaced from an account bearing Prince’s name. The post, dated February 19, appears to reference the victim by age and first name, and lists an address on Westminster Place in Lafayette. The message reads, in part: “If you need the chaos of the supernatural to end [redacted], 34 aka the eye resides at [redacted] westminster pl lafayette ca. Go with God.” A comment attributed to the same account adds: “Can someone please kill this man.”

That post was deleted after the killing came to light. Investigators have not publicly confirmed whether the account belongs to Prince or addressed its contents directly, but the post’s existence raises urgent questions about whether this violence could have been prevented. A public threat naming a specific person at a specific address, posted more than a month before a stabbing at that same address, sits in a grim category of warnings that, in hindsight, seem impossible to ignore.

Neighbors told reporters they recognized the suspect when he was taken into custody. They also said they heard an argument inside the home Saturday morning before police arrived. The exact nature of the relationship between Prince and Jaber has not been disclosed by authorities. No motive has been officially established.

Prince remained held Monday on $1 million bail, according to reporting from Bay Area News Group.

The case puts a sharp focus on a persistent gap in how social media threats get reported, reviewed, and acted upon. Platform moderation rarely catches low-follower posts before something happens. Law enforcement agencies are often poorly positioned to monitor or respond to threats posted weeks before any crime occurs, especially when no formal report is filed. If neighbors or acquaintances saw the February post and did nothing, that is not necessarily a failure of character. Most people do not know what to do with online content that reads as disturbed but has not yet crossed into an obvious criminal act.

California law does allow for gun violence restraining orders when someone poses a credible threat, and similar legal tools exist in the context of stalking and criminal threats charges. Whether any of those tools could have applied here, and whether anyone had knowledge of the post before Saturday, are questions investigators will likely need to answer.

For Lafayette, the killing ends a four-year stretch without a homicide in a community that rarely makes news for violent crime. The suburb of roughly 25,000 residents ranks among the most affluent in the East Bay, a place where most of the civic anxiety tends to run toward traffic, school enrollment, and hillside development. Violent death at this scale is not part of the local rhythm.
