State v. Timley, 469 P.3d 54

Background

On June 13, 2014, Jermel Robbins was fatally shot; witnesses described a blue/gray Dodge Magnum and a passenger who fired from the vehicle.
Police linked a Magnum (registered to Jazmine Christopher) and suspected Cortez Timley, Christopher's boyfriend; Timley was arrested the same day in a different car and a broken Kyocera flip phone was recovered from the seat where he had been sitting.
Sprint records (PCMD and tower data) for the recovered phone were admitted without objection; Detective Broxterman created maps from that data and testified about tower connections and a 2.63-mile estimated distance from a Topeka tower to both the handset and the crime scene.
Timley presented an expert (Dreux Doty) who emphasized the PCMD estimates were not exact GPS and could be inaccurate, though he agreed 2.63 miles was a rational estimate.
Timley was convicted of first-degree premeditated murder; he appealed raising prosecutorial error (misstating phone location), improper admission of Broxterman’s maps/testimony, failure to sua sponte instruct on a lesser included offense (intentional second-degree murder), an asserted due process violation from the lack of lesser instructions, and cumulative error.
Kansas Supreme Court affirmed the conviction, finding at most harmless error on the challenged prosecutor statement, Broxterman’s testimony admissible without an expert, the failure to give a lesser-included instruction was not clearly reversible, and no due process violation.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Prosecutorial statements about phone location	State argued remarks were fair argument and reasonable inference from Sprint data and mapping	Timley argued prosecutor mischaracterized PCMD as exact and vouched for phone being 'exactly' at shooting site	Remarks in closing were within wide latitude; the single opening statement overstated but was harmless beyond a reasonable doubt
Admissibility of Broxterman's maps/testimony	State argued Broxterman could lay foundation and present maps from admitted Sprint records as a lay witness	Timley argued Broxterman lacked specialized expertise to infer phone location and maps required an expert	Court held maps/testimony admissible; lay testimony permitted to show general trajectory and tower connections without expert
Failure to sua sponte instruct on intentional second-degree murder	State implicitly argued instruction unnecessary given evidence of planning and context	Timley argued jury could have found a crime of opportunity and instruction was warranted	Court found an instruction would have been legally appropriate but omission was not clearly reversible; no firm conviction jury would have decided differently
Due process claim from no lesser-included instructions	State argued no constitutional violation where no Beck extension required in noncapital case	Timley argued failure to give lesser instructions deprived jury of a valid option and violated due process	Court reaffirmed prior holdings: no due process violation in noncapital case where instruction not requested; Becker/Love control
Cumulative error	State argued errors were isolated and unrelated	Timley argued multiple errors together undermined conviction	Court rejected cumulative-error claim because only harmless error identified and errors were unrelated
