A second woman has been charged in an assault at a St. Paul Taco Bell that started with a dispute over a food order, during which one customer was reportedly hit with a tire iron and another was jumped in the parking lot.

Krystynn Shirelle Mems-Collins, 26, of St. Paul threw a chair over the counter at employees and punched two customers, according to a criminal complaint charging her with third-degree riot and fifth-degree assault.

Laresha Marie Uting, 24, of St. Paul was charged Friday with one felony count of second-degree riot with a dangerous weapon.

A third suspect, identified in a criminal complaint as “Guns,” has not been charged. But St. Paul police Monday arrested one Joe Willie Ross of St. Paul in the incident. Ross had not been charged as of Tuesday afternoon.

The incident occurred about 9 p.m. May 26 at the Taco Bell near White Bear and Nevada avenues in the Greater East Side neighborhood.

According to criminal complaints, Mems-Collins, Uting and a male ordered food at the drive-through and came into the restaurant to complain that their order was wrong.

They were allegedly belligerent and swearing at employees, so a regular customer — a 15-year-old boy identified as N.S. — tried to intervene. They argued and the three left the restaurant, but returned moments later.

Mems-Collins picked up a chair and threw it over the counter at employees, a criminal complaint said.

Then she and her friends turned on the boy.

Uting had retrieved a tire iron from her car in the parking lot, which she gave to the male, identified as “Guns,” who used it to hit the boy in the head. Mems-Collins then punched the boy, the complaint said.

When the three left Taco Bell, Mems-Collins and her male acquaintance allegedly attacked a customer entering the restaurant.

Mems-Collins has her first court appearance Wednesday morning. Uting has a hearing June 29.
