A 22-year-old sailor has been arrested and charged with vehicular homicide after causing a car crash May 28 that killed a woman on Guam.

Petty Officer 3rd Class Raul Arnaldo Mastrapa, a crewmember aboard the submarine USS City of Corpus Christi at Naval Base Guam, is in police custody at the island’s Hagatna Holding Facility, said Aida Pierce, a highway traffic investigator with Guam Police Department.

In addition to vehicular homicide, Mastrapa was charged with reckless driving causing injury and driving under the influence of alcohol causing injuries, Pierce said.

He appeared in Guam Superior Court on May 29, Navy officials confirmed last week.

Mastrapa was driving northbound on Route 2A, about a quarter mile from the back gate of the base, when he lost control of his 1998 Jeep Cherokee Sport and veered into the oncoming lane, striking a 1992 240SX Nissan, according to Guam police. The Nissan spun and was struck from behind by a 1998 Dodge Durango.

The driver of the Nissan, Agat resident Lila Ann Quichocho, 39, suffered massive head trauma and was pronounced dead at 6:59 p.m. at Guam’s Naval Hospital, Pierce said.

Mastrapa and his passenger, also a sailor, sustained nonlife-threatening injuries, according to Pierce.

Mastrapa’s blood-alcohol content was 0.289, she said — three times Guam’s legal limit. Police are still investigating how fast Mastrapa was driving, Pierce said.

Senior Chief Jonathan Annis, Naval Base Guam spokesman, said the Navy extends its regret to the victim’s family and to the Guam community.

“The Navy is saddened by this tragic event,” he said. “This incident has the attention of the highest levels of Navy leadership. Stopping DUI is a top priority for the Navy and we are united in taking all appropriate measures to prevent this … from ever happening again.”
