Arteise M.N. Brown was a 24-year-old mother of two who was killed on the evening of April 28, 2015, in Wilmington, Delaware. Around 8 p.m. she was in the 600 block of West Sixth Street, walking with another person and two children when the group stopped so a child could tie a shoe. Moments later at least 13 shots were fired in the crowded West Center City neighborhood. Brown was struck in the lower back and later died at Christiana Hospital despite CPR on scene and en route. A 19-year-old woman, Alisa Dollar, was also wounded and survived.

Witnesses described a man dressed mostly in black with white shoes firing from near a daycare; one account said the shooter ran north and entered a white vehicle. Investigators initially struggled to obtain a reliable identification. Families and community members rallied after the killing and a $10,000 reward was offered for information. On May 20, 2015, police arrested 25-year-old Mateo Pinkston and charged him with second-degree murder and related offenses, but prosecutors dismissed those charges in June 2016 after a key witness recanted an identification and other witnesses could not identify the shooter. No one has been convicted of killing Brown, and who fired the fatal shot remains unresolved.

If anyone was present that night or has information about the shooting, please share what is known with investigators.
