What was the motive here? I don't understand. Why did this happen? It maeks no sense to me.

On the evening of June 24, 2022, gunfire broke out on the 4500 block of Hamilton Avenue in Pine Lawn, a suburb of St. Louis. Officers arriving about 7:15 p.m. found two young men who had been shot; both were pronounced dead at the scene. One victim was identified as 19-year-old Jacob Pierce of Arnold, a Caucasian male. The other victim was 24-year-old Markco Willingham of St. Louis.

The Major Case Squad of Greater St. Louis took over the investigation, treating the double killing as a targeted act of violence though no specific motive was released. Investigators focused on a person of interest and later arrested 20-year-old Trevontae Sain of Berkeley, Missouri. Sain was charged with two counts of first-degree murder and two counts of armed criminal action and held on a $500,000 cash-only bond as the case proceeds through the courts.

If anyone has information about Jacob Pierce, his movements that evening, or the shooting on Hamilton Avenue, please come forward to investigators.
