A 30-year-old man in Washington state has been charged with killing one of his grandfathers and remains a suspect in the death of the other.
Island County prosecutors say Joshua David Lambert stabbed his paternal grandfather, 80-year-old George Lambert, on Monday with what appeared to be an ice pick.
George Lambert's 66-year-old sister was struck in the head and bound with tape. Investigators say she later was able to call for help and identified Joshua Lambert as the attacker.
Lambert is also a suspect in the death that day of his maternal grandfather, August Eisner.
The transient from Oak Harbor is set to be arraigned Oct. 17 on murder and kidnapping charges. Prosecutors say he has a long criminal record, including convictions for assault with a deadly weapon.
