Most Recent Reflection
View all 23 ReflectionsThad, it must have been so hard to leave your family at such a young age. I can imagine that you fought as hard as you could to stay alive but God had different plans for you. As I read through these tributes to you, I now understand what my friend, your sister, Lois has gone through. She told me how her brother Thad had been taken from her at such a young age. But I understand how each time there is a fallen officer, she relives the trauma of how her brother, her protector was taken from her family. Everyday, I'm sure she was reminded that you were gone. Caring for her both her mother and father in there later year, she missed having a partner to share tough moments and good memories.
Please if you can visit her in her dreams and let her know how proud you are of her... she'll always be a caregiver ... remind her to take care of herself and that there are people that care for her too. And to reach out to them.
