This sentence will be served concurrently with an existing three-year sentence related to a separate drug offense.

Authorities revealed that Arnold was involved in drug dealing and was armed when Officer Rivera and her partner came across him on the night of June 5, 2025. This encounter took place near the intersection of 82nd Street and Drexel Avenue in Chicago’s Chatham neighborhood.

Prosecutors said the officers tried to engage with Arnold after they noticed what they thought was a gun with a drum magazine, and Arnold ran, prompting a pursuit.

The pursuit led the officers to a nearby apartment, where authorities say Arnold had guns and was preparing drugs for sale.

That is where investigators say Rivera and her partner encountered Arnold’s co-defendant, Adrian Rucker.

Prosecutors said police body camera video and security video in the apartment captured Rucker pointing a rifle at officers from behind a couch in the apartment.

Authorities say that’s when Rivera’s partner lost his footing, and his weapon accidentally discharged, striking Rivera and killing her.

Rucker is due in court May 12.
