A 37-year-old man is being charged in the second degree murder of his mother-in-law.
The 66-year-old victim died in a fire in a Richmond home early Monday morning.
Her 13-year-old grandson, who was also in the home, is in hospital but not expected to survive.
The Integrated Homicide Investigation Team says the suspect, who cannot be named, will appear in court on the charge on Friday.
Police say he had not been living in the Richmond home since becoming estranged earlier in the month.
