State v. Wells, 2022 Ohio 30

Victim Kenny Danner and defendant Gregory Wells were in an on-again/off-again love triangle with Kiiesha Battle; past physical incident in 2019 between Danner and Wells occurred.
On October 12, 2020, Wells drove up to Danner’s car and fired multiple rounds through the passenger side; Danner was shot at least six times and severely injured.
Danner identified Wells immediately (911 call, hospital, trial). Surveillance video, Google cell-site/location data, and other evidence tied Wells to the scene; Wells admitted shooting but claimed heat-of-passion, no intent to kill.
Wells was charged with attempted murder (with firearm specification), felonious assault, improper handling of a firearm in a motor vehicle, and having weapons while under disability; convicted by jury and sentenced to 18½–24 years.
On appeal Wells raised five assignments of error focusing on: (1) alleged Crim.R. 16 discovery violation (itemized witness list misfiled by State), (2) admission of OSHP supervisor Jeff Moran’s testimony about cell-phone location data (claimed expert testimony), and (3) cumulative error.
The trial court denied relief on discovery and witness-exclusion requests; the appellate court affirmed, finding no willful discovery violation, no prejudice, and that Moran testified as a lay witness.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did the State violate Crim.R.16 by failing to provide an itemized witness list timely?	State: Provided police reports/statements with witness IDs; the itemized list was inadvertently filed in another case but not willful; defendant not prejudiced.	Wells: Late production (filed in wrong case) denied opportunity to prepare; sought continuance/exclusion.	Court: No abuse of discretion; mistake was not willful, defendant had names in reports, and no prejudice given overwhelming evidence.
Was Jeff Moran’s testimony about Google cell-location data inadmissible expert testimony?	State: Moran was not offered or qualified as an expert and only mapped latitude/longitude—lay testimony based on provided data.	Wells: Moran’s testimony involved technical analysis of cell-location data and required expert qualification.	Court: Moran testified as a lay witness (no specialized opinion); admission was within trial court’s discretion.
Did cumulative trial errors deprive Wells of a fair trial?	State: No significant errors occurred; any minor issues were harmless.	Wells: Combined errors (discovery, expert testimony) produced unfair trial.	Court: No multiple harmless errors found; cumulative-error claim fails.
