A driver and passenger were killed in a single-car accident early Sunday morning on I-95 in Middletown Township, Bucks County.

State police said that Richard Nagbe, 25, of Upper Darby was driving south on iced-up I-95 about 3 a.m. when his 2000-model Mitsubishi Montero struck a guard rail, rolled over an embankment, and came to rest on the westbound shoulder of the Pennsylvania Turnpike, which I-95 crosses.

Nagbe and a female passenger, Dehkontee Kpou, 31 of Philadelphia were pronounced dead at the scene, police said.

Two other passengers - Giftens George, 23, of Philadelphia, and Emmanuel Ninwillay, 33, also of Philadelphia - were taken to St. Mary's Medical Center with injuries, police said.

Police said Nagbe lost control of his SUV, "due to icy road conditions."
