CLAYTON — Kcoree Warren was offered $12,000 to stay quiet.
In May, two people showed up at his Ferguson home and tried to bribe him to not cooperate in a rape case, court records say. Warren, 44, had reported the assault to police.
Warren refused to take the money.
Six weeks later, he was shot dead outside his front door while his two daughters were inside.

Lavor Harmon
Then, just three hours after the shooting, Warren’s suspected killer was found dead in 51. He had been shot in the head. A nearby white SUV had been burned, court records say.
Authorities have now tied the two men’s murders to the rape case against Lavor Harmon, 39. They’ve also charged his sister, Lavonda Harmon, with tampering with a witness, saying she was involved with the $12,000 bribe.

The connections were laid out in records filed this week by 51 County Assistant Prosecutor John Schlesinger, who asked a judge to increase Lavor’s bond because of the new revelations.
Schlesinger wrote that Lavor’s criminal history shows he “is involved in organized criminal behavior.”
“The facts of the case are alarming enough,” Schlesinger wrote.
He added that “investigations have revealed that (Lavor), his family members, and associates have engaged in criminal activity that demonstrates the significant danger he poses to the victim and community.”
Judge Richard Stewart on Tuesday increased Lavor’s bond from $150,000 to $2 million cash-only.
As of Wednesday afternoon, both Lavor and Lavonda were in custody at the 51 County jail. Lavonda posted a $100,000 cash-only bond after being arrested, court records say.

Lavonda does not yet have a defense attorney listed in court records. Lavor’s attorney, Jordan Wellinghoff, said he had not seen any evidence and declined to comment on the case.
The 51 County Prosecuting Attorney’s Office also declined to comment.
“This is a very active and ongoing investigation,” said spokesman Chris King. “So we are not talking about it.”
Warren’s family said this week they were not speaking with the press out of fear for their safety. But fundraiser for the family called Warren a loving father and friend, a business owner, and “a single dad of two beautiful daughters and a son that he worked hard to raise.”
His Facebook page is full of posts from people grieving his death.
“He helped me and my family so many times without being asked that I can’t even count,” wrote one friend, noting Warren was a plumber. “This wonderful man who only ever spread ‘One Love’ deserved so much better.”
Earlier this year, Warren filed a police report alleging Lavor, of Ferguson, had sexually assaulted a teenage girl in mid-March.
In May, prosecutors filed four second-degree statutory sodomy charges against Lavor. The charges say he met a 15-year-old girl who was walking home from school. The two exchanged phone numbers and, on March 21, Lavor took her shopping and then to her house, where he sexually assaulted her, charges say.
Ten days after the rape charges were filed, Lavonda showed up at Warren’s home, where the bribe was offered, records say. A man with her was not identified in the records.
51 natives
Prior to his arrest in June, Lavor was living with his mother in a three-bedroom ranch home in Ferguson near Forestwood Park — just half a mile from Warren’s home, court records show.
He was working for an in-home health care company. And he was under federal supervised release for three prior convictions.
In 2006, he was charged with having 50 grams of cocaine and crack cocaine and dealing it. He pleaded guilty to some of those charges and was sentenced to 70 months in prison, followed by three years of supervised release.
Six years later, he was federally indicted again, accused of possessing and dealing cocaine with three other defendants. He pleaded guilty and was sentenced to 63 months in prison, followed by four years of supervised release.
Then in 2019, he was indicted for possessing and dealing fentanyl and sentenced to 68 months in prison, which ran consecutively with the 2012 case’s sentence, followed by three years of supervised release.
A federal database says Lavor was released from prison in early January.
Lavonda, his sister, married a 51 man in 2017 in Las Vegas, court records show. They separated a month later, according to a divorce petition Lavonda filed in 2019.

Lavonda Harmon
Both Lavonda and her ex-husband were unemployed at the time, the petition said.
She moved to Houston, Texas in 2021, public records show. Her Houston address is still listed as her home in court records.
A second body
On Warren’s porch in May, Lavonda tried to convince him not to participate in the prosecution of her brother, police say.
The unidentified man with Lavonda then offered Warren $12,000, police wrote in charging documents. Warren didn’t take the money.
Six weeks later, on the afternoon of July 8, someone came to Warren’s home on Bayview Drive and shot him.
Investigators at the time said they were looking for a man in his 20s who was seen fleeing the scene in a white SUV.
Then, just hours after Warren was shot, 51 police reported they found a man shot dead in the 3100 block of Vine Grove Avenue. Police later identified the man as 19-year-old Andrew Klaus of Imperial.
Prior to that identification, social media posts reported that Klaus had been missing since July 8.
His family said he was last seen leaving in a white SUV near Paddington and Bermuda drives, 2 miles south of Warren’s home.
