The 19-year-old son of an Episcopal priest has been charged with capital murder in the deaths of his parents and little brother in Houston, the Associated Press reports. 

Isaac Tiharihondi was arrested in Jackson, Miss., early Wednesday morning and remains in jail as he awaits extradition to Texas, the news site notes. The family—Israel Ahimbisibwe, 51; Dorcus Ahimbisibwe, 47; and 5-year-old Israel Ahimbisibwe Jr.—were found dead in their Houston apartment Monday.

Details about how they died have not yet been released as investigators await autopsies. According to AP, Houston police spokesman Victor Senties did not offer comment on motive.

The congregation at Houston’s Church of the Redeemer, where Israel Ahimbisibwe served as vicar, became concerned when the family did not show up for Sunday service and then could not be reached Monday.
