Shaft D. Wilson Jr., 19, was shot and killed during a Halloween party in Lake Forest on October 29, 2017. The shooting occurred about 12:05 a.m. in the 1300 block of West Estate Lane East after an argument among several partygoers; someone produced a firearm and opened fire. The gathering had been promoted on social media and drew an estimated 150 to 200 people from southern Wisconsin and northeast Illinois. The homeowners were not present; an adult relative had allowed an acquaintance to host the event.

A 20-year-old woman from Waukegan was injured by trampling as guests fled and was treated and released. Wilson’s family held a Celebration of Life on November 8, 2017, and he was buried at Mt. Olivet Memorial Park in Zion. His parents are Latasha McKelvy and Shaft D. Wilson Sr.; he is also survived by three brothers, a sister and other relatives.

Does anyone who attended that party or was in the neighborhood that night have information that could help the investigation?
