DES MOINES, Iowa (AP) — Des Moines police say a driver accused of hitting and killing a pedestrian provided a false name to officers.

A police news release Monday said officers expect more charges will be leveled against 22-year-old Oleaf Teoh, who they say provided a different name proved false by fingerprint examination.

Police say a man walking west was struck from behind around 9 p.m. Sunday by a sport utility vehicle. The man's been identified as Des Moines resident Matthew Otto.

Police say Teoh is charged with vehicular homicide while driving under the influence, leaving the accident scene and charged with related crimes. Police say 3-day-old and 6-year-old children were in the SUV when Otto was struck.

It's unclear whether Teoh has an attorney who could comment about the case.
