People v. Wallace, 42 N.E.3d 945

In March 2006 Corrie Wallace was identified at the scene of a shooting that killed Hallie Parish; Wallace was detained at the scene, later arrested, and convicted in 2008 of first‑degree murder and aggravated battery.
Physical evidence: mask found in a nearby residence with Wallace’s DNA, ammunition in the house matching the gun used, and gunshot residue on Wallace’s hands. Witnesses Tonya Dandridge and Zatella Bridge placed Wallace at the shooter’s conduct (masked, fleeing, returning unmasked and taunting).
At trial, two witnesses present in the car (Joe Williams and Charles McAfee) could not identify the shooter; Williams was shot and later claimed an anonymous apology from someone who said they were the shooter (trial court excluded that testimony).
In 2013 Wallace filed a 207‑page pro se postconviction petition asserting (among many claims) newly discovered evidence of actual innocence (affidavits from Darius Foster and Adrian Ellis implicating another shooter, Conley Ratcliffe) and ineffective assistance for failing to move to quash/suppress the arrest.
The trial court summarily dismissed the petition as frivolous and patently without merit; Wallace appealed the dismissal.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Wallace stated an arguable claim of actual innocence based on newly discovered evidence (Foster and Ellis affidavits)	The State: affidavits are cumulative/inadmissible or not newly discovered and thus insufficient	Wallace: Foster saw Ratcliffe with a gun fleeing the scene; Ellis says Ratcliffe confessed in jail — both newly discovered and exculpatory	Dismissed — affidavits fail: Foster was known to defense before trial (no due diligence), Foster’s account would not conclusively exonerate Wallace, Ellis’s affidavit is hearsay and duplicates evidence already available at trial
Whether counsel was ineffective for not moving to quash/suppress the arrest (and appellate counsel ineffective for not raising it)	The State: there was probable cause for arrest; any motion would have been futile	Wallace: Officer Stubler arrested/detained without probable cause; counsel deficient for not moving to suppress	Dismissed — detention was supported by reasonable suspicion and, given on‑scene witness information (including Dandridge), arrest was supported by probable cause; counsel’s failure to move would have been reasonable and not deficient
