Roseville Alnwick Drive Murders-Suicide Update

Roseville Police detectives are continuing their investigation into last night’s shooting at a home in the 1600 block of Alnwick Drive in west Roseville. The incident appears to have been a double homicide-suicide.  Investigators believe that the shooter is one of the three deceased persons, and that there are no other suspects at large.

At 8:57 p.m. Tuesday, September 15, a 16-year-old male called the Roseville Police Department to report that a male armed with a handgun had forced entry into his home, and that he believed the male had shot his parents. Officers surrounded the residence, and after unsuccessful attempts to make contact with anyone inside, made entry at about 1:40 a.m.  Officers discovered three deceased people inside an upstairs bedroom: the boy’s 49-year old mother, his 52-year-old father, and a 35-year-old male, whom detectives believe was the shooter.

The preliminary investigation indicates that while the reporting party did not know the shooter, the shooter was known to his parents.  Detectives are working to determine the relationship between the shooter and the victims, and the shooter’s motive.
