New details have emerged on the murder of Margaret Mbitu who was found dead inside her boyfriend’s car at Logan Airport in the US.

Investigators pieced together Mbitu’s last moments alive and identified her 40-year-old Kevin Kangethe as the prime suspect.

Rose Mbitu, the deceased mother told Boston 25 News the suspected killer was someone her daughter was dating, adding that her daughter was trying to break things off with him.

“The entire family, everybody’s down. I’m not myself right now. This is heartbreaking.” The grieving mother added.

Kangethe is suspected to have committed the heinous crime before boarding a flight to Kenya, leaving Mbitu’s body in the vehicle.

The 31-year-old was reported missing by her family on Monday, according to Massachusetts State Police.

Her body was found with visible knife wounds on the face and neck as well as on her side near the chest area.

“Evidence indicates that she was the victim of a homicide,” state police said in a statement.

“We urge this suspect to turn himself in to authorities before he or anyone else gets hurt. We are making every effort possible to apprehend him and to begin the process of seeking justice for Margaret Mbitu and those mourning her tragic death,” Suffolk County DA Kevin Hayden said in a statement.
