SANTA FE, N.M. — The New Mexico Supreme Court has upheld a man’s murder convictions in the 2010 robbery killings of a man and woman at a home in the Albuquerque area.

The high court issued the ruling Thursday in an appeal filed for Rigoberto Rodriguez, who was convicted in the shooting death of David Maldonado and the fatal stabbing of his ex-wife, Connie Maldonado.

The ruling overturned three of Rodriguez’s four convictions of conspiracy, ruling that those allegations should be included in a remaining conspiracy conviction.

Much of the prosecution’s case was based on law enforcement testimony about phone calls between Rodriguez and co-conspirators and between Rodriguez and at least one victim. The trial judge allowed use of that evidence, and the Supreme Court upheld it.
