A teenager killed his pastor father, Sunday school teacher mother and five-year-old brother after his parents found out he’d lied about joining the Marines, according to authorities.

Isaac Tiharihondi, from Houston, Texas, was arrested and charged with capital murder after police found him Jackson, Mississippi around 2.30am on Wednesday.

His arrest comes two days after the bodies of Episcopalian Reverend Dr. Israel Ahimbisibwe, his wife Dorcus and their son, Israel Jr., were found stacked up inside their Houston apartment.

Isaac Tiharihondi,19, used items including a bat, a hammer and a lamp to beat his parents to death, while his little brother had been stabbed with a kitchen knife, according to the criminal complaint.

Tiharihondi had told friends and family that he had joined the Marines and was leaving at the end of the month – but his parents did not believe him and planned to confront him about it, ABC13 reported.

Recruiters in Houston said there is no record of him ever enlisting in the Marines.

Neighbors said they last saw him at the home on Friday evening but had not seen him since.

He is now awaiting extradition back to Harris County.

Their bodies were found in a back bedroom by firefighters on Monday morning after parishioners raised the alarm when they failed to turn up to church on Sunday.
