Tyler Koscinski, Mason Santiago Obituary, Death – Two young athletes from the Chicago area, who were described by family members as best friends, tragically lost their lives in a car crash over the weekend. The accident occurred early Sunday morning at 4:22 a.m. on Interstate 80, between La Grange Road and Harlem Avenue, in Tinley Park, a suburb southwest of Chicago.
The crash involved a Dodge Journey SUV and a truck-tractor semi-trailer, but details about the circumstances surrounding the collision have not yet been released by authorities. The investigation is ongoing. The Will County Coroner’s Office identified the two victims as Tyler Koscinski, 20, and Mason Santiago, 19, both residents of New Lenox.
Tyler Koscinski, who had just celebrated his 20th birthday, was a recent graduate of Lincoln-Way West High School. During his time there, he played both football and baseball and was remembered for his dedication to sports. He was also part of the Illinois Premiere Baseball team. A memorial foundation established in his memory described him as a cherished community member and a passionate athlete whose love for sports was a defining aspect of his life.
Lincoln-Way West Athletics posted a tribute on social media, highlighting Koscinski’s role in the school’s sports history. He was praised as a great teammate and a key player in securing one of the school’s most significant victories, including a memorable play that helped win their first sectional title. His legacy, filled with unforgettable moments on and off the field, left a lasting impact on those who knew him.
Koscinski’s obituary noted that everyone who knew him loved him for his many unique qualities.

He was known for his infectious energy, whether dancing or cracking jokes, always bringing smiles to those around him. His family and friends cherished him deeply, and his memory will live on through them.
Mason Santiago, the second victim, was also a talented athlete. A graduate of Providence Catholic High School, he played football and continued his athletic career at Saint Xavier University in Chicago. Santiago was remembered as a driven and focused individual who always gave 110% in everything he did. His obituary described him as a fierce competitor who was determined to excel in his position, never cutting corners, and constantly striving to be the best.
Even after graduating from Providence Catholic, Santiago would return to mentor younger football players, a reflection of his dedication and commitment to the sport. He had just started his sophomore year at Saint Xavier University, where he was studying sports communication.

Santiago’s mother echoed this sentiment, describing the boys as being “attached at the hip.” On the night of the crash, they were returning home from Saint Xavier University, where they had spent time together.
In the wake of the tragedy, fundraising pages were set up to support the families of both Koscinski and Santiago. The pages have collectively raised tens of thousands of dollars, with Koscinski’s fund reaching $37,000 and Santiago’s reaching $41,000.

She referred to Tyler as “the light of our lives,” emphasizing how much he was adored not just by his family, but by everyone who knew him.
Tyler’s older brother, Connor, shared a touching memory of one of the last messages he received from his younger brother. The message came in the form of a TikTok video titled, “Some things I don’t always tell my brother, but hope he knows,” and included heartfelt sentiments like “you’ll always be my No. 1 best friend” and “I would choose you to be my brother in every lifetime.”
In his eulogy, Connor described Tyler as having a heart of gold and a gentle but strong spirit. He expressed his gratitude for the close relationship they shared, reflecting on how Tyler had shown him the true meaning of being a big brother.
Santiago’s funeral services were scheduled to take place over the weekend, as family and friends prepared to say their final goodbyes to another beloved young life taken too soon.
