The man that was struck was rushed to the hospital in critical condition. On Tuesday, police say that man died from his injuries.

He was identified as 67-year-old Kirk King. He fought to stay alive for nearly three weeks.

“It was an average, regular day for my dad that day. He was just going to go and get some groceries and maybe just walk around and go back to his apartment,” said Christy Mask.

Mask said her dad was a free spirit and was always fond of where he lived and often walked around playing his harmonica.

“Loved his neighborhood and he loved downtown, and he kept to himself,” she said.

Officers arrested the suspect – 24-year-old Daniel Tui – back on the day of the incident for felony assault and elder abuse charges.

With King’s death, Tui is now facing added charges of homicide.

No motive has been identified for the assault. Tui and King did not know each other, police say.

Mask can’t imagine what her dad experienced in what would be his final moments, leaving people with this message.

“For us, it’s shocking because I know he was just doing what he normally does,” she said. “I would tell everybody in the community that my dad was a great guy, but y’all need to watch your back because you never know.”
