The family of Redeemer Episcopal Church in Houston were still reeling from the news their pastor and his family had been murdered when they suffered a second blow.

The son of Pastor Israel Ahimbisbwe has been arrested in the murder of his father, mother and brother.

Houston police say that 19-year-old Isaac Tiharihondi has been charged with two counts of capital murder and was being held in custody in Mississippi where he fled after the killings.  He covered the bodies with blankets and towels in the back bathroom of the apartment where the victims were found Monday.

A member of the church told a local TV station that she had lunch with the accused killer after police say he committed the crime.

“It’s devastating. It’s sad. It’s unexplainable,” Nancy Taylor, who attends Church of the Redeemer, told KHOU.  “We had lunch, we sat, we chatted, we talked, we laughed. It was just a real enjoyable experience and time together. … Good kid, polite, nice, respectful, grateful.”

“While I am relieved authorities have found Isaac, I am heartbroken that he has been charged with capital murder. This only adds to the tragedy of their deaths and raises more questions than it answers,” Rt. Rev. C. Andrew Doyle, Episcopal Bishop of Texas said in a statement.
