Phoenix police are searching for 18-year-old Markelle Jimerson, who has been named a person of interest in a June triple shooting that left three people dead. Detectives say the case is still active as they track leads, comb through tips and review video footage, and they are urging anyone who knows something to speak up.

According to Silent Witness, the nonprofit is offering up to $2,000 for information that leads to a homicide arrest. The group runs phone tip lines and an online form so people can submit information anonymously.

Police name person of interest

Phoenix police have identified Jimerson as a person of interest and linked him to a fatal triple shooting in June, according to FOX 10 Phoenix. The outlet’s report did not include the exact location of the incident or indicate whether any charges have been filed.

How to submit tips

Silent Witness directs anyone who wants to share information anonymously to call 480‑WITNESS (480‑948‑6377) or use its online tip form. Spanish speakers can call 480‑TESTIGO (480‑837‑8446). Per Silent Witness, homicide tips may qualify for the higher reward amount, and tipsters can remain anonymous.

Context in Phoenix

The deadly June shooting is the latest violent incident to shake Phoenix neighborhoods this month. As reported in a story on a June 13 triple shooting near 7th Avenue and Baseline Road, that separate incident left one person dead and two others injured, underscoring growing community worries about public safety.

Legal note

Being named a person of interest is not the same as being charged with a crime. FOX 10 Phoenix reported that there were no arrests or formal charges in the June triple homicide at the time of its coverage. If charges are filed, they would come through the Maricopa County Attorney’s Office and appear in court records.

Anyone with information that could help the investigation is urged to contact Silent Witness or Phoenix police so detectives can follow up. Tips may qualify for a reward and could be key to moving the case forward.
