Messages of condolences have poured in for the teenager's family.

From the Tandragee area, the teenager passed away in hospital on Wednesday afternoon (18 September) from injuries sustained following a collision on the Cladymilltown Road on the evening of the previous Sunday.

This was when two vehicles - a blue Volkswagen Jetta driven by Daniel and a blue Volkswagen Touran - collided.

The other driver remains in a critical condition in hospital.  

Mr. McCallister's death notice on the Funeral Times website reads:

"McCallister, September 18th, 2024, (suddenly) Daniel Joseph, dearly loved son of William and Barbara, 32 Ballyshiel Road, Clare, Tandragee, much loved brother of Sarah, Jack, Kathryn and Samuel, dear brother-in-law of Adam, cherished grandson of Jackie and Eileen and a dear uncle and nephew."

"Lovingly remembered and dearly missed by his father, mother and his loving family."

Markethill High School, where Daniel was once a student, extended its "deepest condolences" to his family in a social media post.

"On behalf of the entire Markethill High School family, we wish to extend our deepest sympathies to the McCallister family following the loss of their dear son and brother, Daniel, who left us in 2022," it reads.

"The McCallister Family are extremely well known in this area and there is much sadness and shock within the local community. We will continue to keep Mr and Mrs McCallister, Sarah, Jack, Kathryn and Samuel (all past pupils of MHS) in our thoughts and prayers at this very difficult time."

Mr. McCallister's funeral service will take place at St. John’s Parish Church in Mullabrack on Sunday at 2.30pm, followed by a private committal in the adjoining churchyard.
