Family and friends are trying to wrap their heads around the death of 79-year-old Rev. Olander Cassimere and his wife, Alphathad, who was 77.

The couple, who would have celebrated their 55th wedding anniversary on Friday, were fatally shot over the weekend at their home in New Orleans, where Mr. Cassimere was a reverend in the 9th ward. Police say they have leads, and don’t believe the elderly couple were the intended victims, reports WWL.

Explained Police Chief Warren Riley: "Clearly, these two individuals were absolutely innocent. The person that we believe was the target was not there. This type of murder on any day would be shocking — two elderly people who clearly didn’t deserve this, in any way — and certainly on Mother’s Day makes it even more shocking."

This is more than shocking — it’s disturbing, heartbreaking and infuriating.
