The live-in girlfriend of the man accused of killing two women in a crosswalk in a hit-and-run collision in Vancouver will be allowed to live with a couple related to his family.Brandon Smith’s girlfriend, Kalista Andino, and Smith’s mother, Linda Smith, are accused of tampering with witnesses in the vehicular homicide case against him. A court order bars them from having any form of contact with each other or other witnesses in the case.However, Clark County Superior Court Judge David Gregerson today allowed Andino to live with Terry and Maryanna Belland of Washougal, despite objections by Senior Deputy Prosecutor Kasey Vu and a supervised release officer. The Bellands are the parents of Brandon Smith’s sister-in-law, Briana Peterson. Peterson is married to Smith’s half-brother, Craig Peterson, of Camas.Raisa Mosh, 45, and Irina Gardinant, 28, were killed about 8 p.m. Jan. 19 when a white pickup struck them in a crosswalk at Northeast 72nd Avenue and Vancouver Mall Drive. Vancouver police said Smith was the driver. He fled the scene of the collision without calling 911 or trying to help the victims, they said. Mosh’s 12-year-old son also was injured.Since Smith’s Jan. 29 arrest, Andino has been living alone with her 6-month-old daughter in the apartment she shared with Smith at the time of collision.
