Marine Nate Shiel and his wife Peri, Eric Haulcy, and two others injured in three-vehicle collision on Oceanside Boulevard in Oceanside, California

A Camp Pendleton Marine and his wife were among five people injured in a three-vehicle crash on Oceanside Boulevard, friends told NBC 7 Tuesday. Marine Nate Shiel and his wife Peri were rushed to Scripps La Jolla Hospital Monday evening, where Nate is still in critical condition. Oceanside police said Nate was driving a Mazda east on Oceanside Boulevard when a driver in a Chevy Impala traveling west veered into the median and hit the Mazda head-on. He too is in critical condition at Scripps La Jolla. Oceanside police are still investigating if alcohol or drugs were factors in the crash, though they say Haulcy smelled of alcohol when he was in the operating room.
