MINNEAPOLIS — A jury has convicted a Minneapolis man of first-degree murder for shooting his girlfriend and her daughter to death.

The Hennepin County jury took only a couple of hours to convict Gonzalo Galvan late Tuesday afternoon. The 51-year-old will automatically be sentenced to life in prison at his Oct. 6 hearing.

Galvan called 911 last September to report that he had shot 48-year-old Eugenia Tallman and her 15-year-old daughter, Victoria Alvarez. The couple’s seven-year-old son was unharmed but witnessed the shooting.

The criminal complaint says Galvan told police she was leaving him and taking both children.
