The man arrested Tuesday for reportedly attacking a Rexburg couple at their home Monday told his brother he planned to “cap” someone that morning stated a court document.

The Madison County Prosecutor’s Office has charged Pierre Lake, 18, with shooting Ralph Brian and stabbing his wife Karen Brian at their home around 5 a.m. Monday.

The documents report that following the attack, Lake conned campers at the neighboring Eagle Park Campground into giving him a ride back to his Rigby home. The court documents reported that Lake gave the campers a fake name and told them there had been a shooting and stabbing at the trailer court. Madison County Sheriff’s officers later traced Lake to Rigby and arrested him.

Lake is facing four felonies including two counts of attempted murder with “premeditation and with malice aforethought,” one burglary charge and one count of grand theft. Lake faces 15 years in prison with an additional 15 years for a weapons enhancement for each attempted murder charge. He is also facing 10 years for the burglary charges and 14 years for the grand theft charges.

Lake appeared before Seventh District Magistrate Judge David Hunt on Wednesday where he was read the charges he now faces. He is being held on a $1 million bond after the state said Lake was extremely dangerous and might flee should he be given a lesser bond. Lake is scheduled for a preliminary hearing at 1:30 p.m., Oct. 6, at the Madison County Courthouse.

According to court documents, neighbors called the Madison County Sheriff’s office around 5 a.m. Monday after seeing a person dressed in black fighting with and shooting Ralph Brian outside his home.

Court documents state that Lake shot Ralph Brian in the back of the head. It’s alleged that Lake broke into the Brians’ home where he slashed Karen Brian in the face and arm several times. The fight moved outside where Lake and Ralph Brian struggled over Ralph Brian’s gun. A female neighbor reported seeing Karen Brian covered with blood.

“Ralph suffered a gunshot wound to the back of the head. Karen suffered stab wounds to the face, neck and arms,” stated court papers.

Court documents reported that an empty holster was found inside the Brians’ home.

“A Ruger Security 6-357 revolver was missing,” stated police reports.

The Brians are being treated at the Eastern Idaho Regional Medical Center where Karen Brian is recuperating from her wounds. Ralph Brian’s condition remains precarious. The couple’s children have declined comment on their parents’ conditions.
