SAN DIEGO (AP) -- A California man has pleaded not guilty to murder charges in the death of his girlfriend, whose skeletal remains were discovered in Panama two years after she disappeared.
The U.S. Attorney's office says 37-year-old Brian Karl Brimager entered his plea Friday after he was indicted by a federal grand jury in San Diego.
Brimager has been in custody since June 2013 on charges including obstruction of justice and falsifying records related to the investigation into the killing of Yvonne Lee Baldelli.
The 42-year-old woman from Laguna Niguel, California, was last seen in 2011 when she arrived in Panama with Brimager.
A man who was cutting bushes on the island province of Bocas del Toro found a bag containing Baldelli's remains in August 2013.
