Fugitive Bronson Gouveia, the subject of a $1 million warrant in connection with the Dec. 23 shooting of his girlfriend in Waianae, could face federal penalties after drug and firearms charges were filed against him in U.S. District Court on Monday.

Police still are searching for the 41-year-old Gouveia, who is suspected of shooting his 31-year-old girlfriend in the head at a residence near Waihee Place and Waihee Road. He was last seen driving a BMW sedan townbound on the H-3 freeway shortly after the 12:50 p.m. incident.

The victim was transported in serious condition to a local trauma center. Police said the bullet grazed her head.

A $1 million warrant for Gouveia was issued by a state judge on Dec. 27 after an Oahu grand jury returned an indictment that included multiple counts, including second-degree attempted murder.

The new federal charges are based on search of Gouveia’s Waihee Road residence by Honolulu police and a review by the Bureau of Alcohol, Tobacco and Firearms.

Gouveia is charged with possession of a controlled substance with intent to distribute based on the discovery of 1,380 grams of methamphetamine at his residence during the search, and being a felon in possession of firearms after sustaining felony convictions. Gouveia, who has 14 prior felony convictions, kept two rifles (including one semi-­automatic) at his residence, according to the complaint.

The firearms charge represents a federal offense because the rifles were brought to Hawaii via interstate and/or foreign commerce.

He was described as 6-feet-1-inch tall, 272 pounds with brown hair and brown eyes, and is considered “armed and dangerous,” CrimeStoppers said.

CrimeStoppers described the vehicle that Gouveia used to flee as a silver 2008 BMW 7-series sedan with a “Murder 187” sticker on the rear passenger window. The car has tinted windows and Hawaii license plates EF134.
