Man Now Facing First-Degree Murder Charge in Death of Pregnant School Bus Driver

The suspect who police say killed a pregnant Montgomery County school bus driver is now facing a first-degree murder charge in her death.

Thierry Kinshala Nkusu, 33, was previously charged with second-degree murder in the death of 36-year-old Maria Veronica Mbunga. The charge against him was upgraded Monday; he was also ordered held without bond.

Takoma Park police announced Nkusu's arrest Thursday, a day after Mbunga was found suffering from multiple stab wounds inside her Houston Avenue apartment.

Police said they found Nkusu by an elevator near the lobby; he also had a stab wound.

He was taken to the hospital along with Mbunga, but police soon learned his wound was superficial and did not match the story he told officers. Nkusu was later transported from the hospital and taken into custody. 

Mbunga and her unborn child died at the hospital. 

Investigators have not commented on the relationship between the two. Police say the investigation into her death is ongoing.

Mbunga worked for the Montgomery County Public School Transportation System as a bus driver.

Nkusu is scheduled for a preliminary hearing May 27 in Rockville District Court.
