Yatsko's family told WKYC they didn't learn of his death until Tuesday morning:

According to reports, Graziolli broke up a fight between a group of men inside the bowling alley and escorted several of them out of the establishment around 9 p.m. Yatsko later returned and began "viciously attacking" Graziolli, who then shot Yatsko.

Witnesses, including an employee of the Corner Alley Uptown also told authorities they saw blood on Graziolli's face, and he was taken to the hospital with contusions, bruises, and stitches in the mouth. The operations manager of Corner Alley Uptown began to describe the scene to 911 dispatchers by saying, "I know there's blood everywhere."

An investigation is ongoing. The Corner Alley Uptown issued the following statement:

The Corner Alley Uptown in University Circle is saddened by the very unfortunate incident that occurred last night. We remain committed to working with our partners at Cleveland Police, University Circle Police and CWRU police to create a safe and fun environment for all our patrons.
