Two Trenton residents have been arrested by West Windsor police in connection with an August armed robbery at a store in Nassau Park Shopping Center. A third suspect is still at large and being sought by police.

Brandon A. Butler, 31, and Diamond M. Williams, 26, were charged with armed robbery, aggravated assault, unlawful possession of a weapon, possession of a weapon for an unlawful purpose, theft and making terroristic threats for a robbery that occurred at Sally Beauty on Aug. 13.

Police are still searching for Quan’Daesia “Daisy” T. Williams, 21, also of Trenton.

According to Lt. Mark Lee, multiple patrol units were dispatched to Sally in response to a report of a robbery in progress. Police arrived to find that the suspects had fled the scene in a red sedan.

Store employees reported that a male and female accomplice—later identified as Butler and Diamond Williams—entered Sally while both employees were at the back of the store. Butler called for assistance, and when one of the employees came out, he pointed a black handgun (believed to be semi-automatic) at her stomach, Lt. Lee said.

He demanded money from the register and pulled the slide back on the handgun. The employee opened the register and both suspects (who had bandanas covering their faces) stuffed cash into a plastic bag.

Butler then demanded that the employee open the store’s safe, but she did not have the key. Butler then went to the back of the store, where he located the other employee, pointed his handgun in her face, and forced her to open the safe, from which additional money was stolen.

An investigation by officers and detectives eventually identified Butler and Williams as the robbery suspects in the store. Both were taken into custody, charged and sent to the Mercer County Corrections Center.

Lt. Lee said that during the investigation police discovered that Quan’Daesia Williams was also involved in the robbery. An warrant for her arrest was issued, and she has been reported to the National Crime Information Center as a wanted person.

Police are asking anyone with information on Quan’Daesia Williams’ whereabouts to contact Det. Jason Jones at (609) 799-1222,jjones@westwindsorpolice.com, or to call the department’s anonymous tip line at (609) 799-0452.

Officers investigating the crime included Chief Robert Garofalo, Det. Sgt. Steven Skwierawski, Sgt. Kevin Loretucci, Det. Jason Jones, Det. William Jones, Det. Christopher Van Ness, and officers Frank Sabatino, Justin Insalaco, Ted Hojnacki and Brandon Heath.
