A Yucca Valley man is in custody, accused of trying to murder his estranged wife at her home in Big Bear. According to the Sheriff’s department, Marvin Engebretson, 71, of the 7500 block of Palm Avenue, forced his way into his wife’s home, threatened to kill her with a gun, beat her, and held her against her will. His wife finally managed to convince Engebretson to let her go and she notified the Big Bear Sheriff’s department. Marvin Engebretson was arrested at his home January 15 and arraigned last Thursday on charges of attempted murder, assault with a firearm, false imprisonment, threatening a crime, felony spouse abuse, and burglary. Marvin Engebretson is being held at the West Valley Detention Center with his bail set at $1 million.
