The family did not reveal a cause of death in its statement regarding Cox's death:
"Early this morning our families lost a phenomenal human being. Aaron Cox was a tremendous son, brother, and brother-in-law. He had a deep love for his family, and a passionate dedication and commitment to his friends. As our families grieve together, we will also celebrate the memories, the laughter, and the love we each shared with Aaron in the short time we had him.
"He will forever be at the forefront in the hearts and minds of the Cox and Trout families. We will rely on the love and strength of God first and foremost during this difficult and challenging time, as well as our dear family and friends. We thank you for your thoughts and prayers, and our Lord and Savior for His precious gift of Aaron Joseph."
The Angels also released a statement:
Cox was the brother of Trout's wife, Jessica.
