A 50-year-old Vancouver man has been charged in the death of his 72-year old mother, police announced Friday morning.

Richard Glen Shields was charged with the second-degree murder of Ethel Fenotti after police were called to an apartment near 12th Avenue and Main Street around 3 a.m. PT Thursday.

Police have not released any cause of death but said Fenotti's body showed signs of trauma.

Shield has no previous criminal record and the case does not appear to be connected to any other investigation, said police.

The homicide is the fifth in the city for 2012.
