A man awaiting possible extradition to Massachusetts on a warrant alleging he killed his girlfriend and left her body in a car at Boston’s Logan airport escaped from police custody in Kenya, Massachusetts State Police confirmed Thursday morning.

Lowell resident Kevin Kangethe, 40, slipped out of the police station and jumped into a privately-owned minivan, Nairobi police chief Adamson Bungei said. Authorities are searching for him once again, state police spokesperson Dave Procopio said in a statement.

Kangethe had been detained pending a ruling on whether he should be extradited to face a first-degree murder charge in connection with the death of Whitman resident Margaret Mbitu on Oct. 31, 2023.

Massachusetts State Police said in early November that Kangethe had left her body in a car at Logan International Airport and boarded a flight to Kenya. Massachusetts officials worked with Kenyan authorities to locate him, and he was arrested in a nightclub on Jan. 30 after being on the run for three months, authorities said previously.

The officers said that around 4 p.m. on Wednesday, a man named John Maina Ndegwa introduced himself to the officers as Kangethe’s lawyer and said he wanted to speak with his client.

“The officers agreed to his request and removed the prisoner from the cells and took him to [an] office ... leaving them there. After a short while, the prisoner escaped by running away and left the [lawyer] behind,” the report said.

Nairobi police chief Adamson Bungei said he rushed to the station when he learned of the escape. “We have arrested the officers who were on duty when he escaped to explain how it happened. It is just embarrassing to us,” he said.

A police official told the AP that Kangethe said he had renounced his U.S. citizenship. The police official, who insisted on anonymity in order speak freely about an ongoing investigation, said if Kangethe were an American citizen he would have been repatriated without a court process.

The court approved a police application for him to be detained for 30 days while the extradition issue was heard.

On Feb. 2, prosecutor Vincent Monda asked the court to endorse the U.S. warrant for Kangethe’s arrest and issue directions for the extradition proceedings.

The suspect’s lawyer sought directions on surrendering Kangethe to the U.S. and opposed his continuing detention as disregarding his rights.

Mbitu, who worked as a health care aide in Halifax, was last seen leaving work Oct. 30 and was soon reported missing by her family. The preliminary investigation showed Mbitu had left her workplace and traveled with Kangethe to Lowell, the prosecution said.

Police have been ranked as Kenya’s most corrupt institution for decades, and his escape raised suspicions that bribes were paid for his freedom. Other suspected killers have escaped police custody in the past.
