A man who was assaulted seven months ago at a store in downtown Minneapolis has died, and the suspect is now charged with murder, authorities said Wednesday.

Lance K. Grant, 24, of St. Paul, suffered skull and brain injuries at Buzz Mart near the corner of N. 5th Street and Hennepin on Nov. 27, according to the Hennepin County Medical Examiner’s Office.

Terry Williams, 29, of St. Paul, was jailed one day after the incident and initially charged with assault.

He’s now charged with second-degree murder and remains held ahead of an Aug. 6 court appearance.

Grant “never regained meaningful brain function” and had been at a long-term care facility since March, according to the charges. He died June 27 at HCMC.

Store video surveillance showed Williams punching Grant as he was about to leave through the front door, according to the criminal complaint.

Williams then hovered over the fallen and motionless Grant, and punched and stomped on his head before stealing from his pockets, the complaint continued.

Williams, his right hand bandaged, was arrested the next day downtown at the Minneapolis Central Library.

He allegedly told police that he was avenging Grant’s assault on him the previous day.
