Joe - As a fellow graduate of St. John’s High School (Washington DC) and friend I know how wonderful a person you were ! We graduated high school together in June, 1970. We both became cops in adjoining jurisdictions. I was at your Montgomery County, MD police academy graduation. I would like your family to understand that you are still revered and missed by your brother cops ! You were lost to your family, department and community. Even after these years you, Joe, are missed and fondly remembered as a person who placed himself in harms way for the thousands he served ! God Bless you and your family, Captain Mattingly ! You have completed your community service watch but you are NEVER FORGOTTEN !!

I still remember meeting you when I was an officer in South Bethany, Delaware. That was a very short time before this event. Now, I'm working for YOUR agency as are your children. Many positive things have been -- and are still being done to this day -- in your honor.

Always remembered, never forgotten.

The loss of a member of our family is always tough.

Based on the birth year of the Captain, I think he may have been a neighbor off Valley Rd. in Bethesda, MD.

The Joe Mattingly, Jr. I knew lived on the hill above Valley Road. We lived at 6305 Valley Rd.

I did not know he was a Montgomery County Police Captain as i moved south in 1980.

Our family is heavily into Law Enforcement. We ache for his family. The loss is never easy.

I read that he went to St. John's Military High School. I attended Cathedral Latin School, graduating in 1967. I believe my brother was in his age group.

Captain, you are in my prayers. A rosary for your soul will be offered by our family.

I was sure that you had come home and that you were sleeping beside me. They knocked on the door at 7:23. I will always believe you were there, with me. I love you Joe.

I met Joe long ago in the 70's when he first joined the Police Department. I would watch him drive his police car up the driveway at his mom's house. He was one of the reasons I wanted to become a police officer.
RIP Capitan.

Hello Mr. Mattingly,
I'm not sure If you remember me, but I was a friend of your son in Middle school and high school. I was thinking about you today, and remember your warmth and genuinely nice interactions with me as a young middle schooler. I still remember your laugh and the excitement in your voice. God Bless

Joe and I were buddies through St. John's High School in Washington DC. It was a military high school and in our senior year, Joe was my company Captain. He was good with leadership even then. I joined the DC Police within two years of high school. When Joe and I made contact, he discussed his immediate intention of becoming a Montgomery County Police Officer. He was indeed and obviously) excited about the prospect. I strongly suspected he'd be a good Cop, which is exacttly what happened.

As unfortunately happens, we lost contact but had sporadic contact. I did, at his invitation, attend Joe's Police Academy graduation in Gaithersburg at the training facility.

As circumstances would have it, Joe and I worked adjacent police jurisdictions ( DC & Montgomary County ). We had some but not enough contact. I retired from the DC Police in 1988. I did raised my four children in Montgomery County, which is similar to Joe's family situation.

I unfortunately did not learn of Joe's death until several months after it happened. Had I known of his death, I certainly would have acknowledged this tragedy and attended his service.

What I do remember is that Joe was always a great guy in High School and maintained that in years we did have contact. We both discussed how we wanted to be Cops and what that meant to us. As a Cop, it's not difficult to know a good Cop, and Joe was certainly that.

I do regret not having maintained contact or a relationship with Joe. I have met others who knew him in later years. His quality as a person and a Police Officer never lessended.

To Joe's family, I would like to offer my sincere but belated condolences. Having lost a DC Police relative, in the live of duty, I have seen what impact is has on families. Joe's loss was to you and the citizens of the County he served well !

Although I do feel the loss of a bother Police Officer, I am proud to have known him ! He lived his belief in family and community. Not many can say that. His family and Department can ! God Bless you, Joe and the entire Mattingley family.
