People v. Simpson, 29 N.E.3d 546

Background

At ~3:15 a.m. on May 15, 2009, two masked, armed men entered the Voutiritsas home; one struck the homeowner and another restrained the son with attempted duct-taping. Victims called 911 and provided a description of the suspects, their dark clothing, and a late-model dark car traveling south on Roberts Road.
Officer Vaccaro observed a car matching the description on Roberts Road, followed it, and activated his siren after the car’s headlights were turned off; the vehicle turned into a driveway and the engine was shut off. Two Black men were in the front seats.
Officers approached with guns drawn, handcuffed the occupants, conducted pat-downs, found half a roll of duct tape on Dortch, and observed a black mask on the passenger floorboard. The car was later searched and a gym bag in the trunk contained masks, gloves, duct tape, and two loaded firearms.
Crime-scene examiner recovered footwear impressions from the entryway and a checkbook; a State Police footwear expert testified that Simpson’s shoe matched one impression (four comparison points) and Dortch’s boot matched another. DNA from a swab of the homeowner’s hand matched Dortch.
Defendants moved to quash arrests and suppress evidence; the trial court denied the motion. After a bench trial, both defendants were convicted of four counts of home invasion; Simpson was sentenced to 30 years. Simpson appealed.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
1) Lawfulness of investigative stop (Terry)	Officer had reasonable suspicion: call reporting two armed suspects in a late-model dark car headed southbound and Vaccaro observed a matching car near scene at night with headlights off and evasive driving	Stop was unsupported by specific, articulable facts; Vaccaro only saw a dark car and acted on a hunch	Upheld: totality (time, proximity, matching vehicle, lights off, driving conduct) gave reasonable suspicion for Terry stop
2) Pat-down and escalation to arrest / probable cause	Protective pat-down reasonable because suspects were reported armed; discovery of duct tape and mask provided probable cause to arrest	Handcuffing rendered detention an arrest and items found later cannot justify arrest; stop exceeded Terry scope	Upheld: handcuffing here did not automatically convert stop into unlawful arrest; mask and duct tape provided probable cause to arrest
3) Foundation for shoeprint expert testimony	Expert qualified; defense had opportunity to probe basis on cross; Rule 705 allows opinion sans full basis on direct	State failed to establish number/details of comparison points on direct, so foundation inadequate; plain error review warranted	Admitted: no plain error; missing details affected weight, not admissibility; cross-examination revealed four comparison points
4) Sufficiency of evidence (guilt beyond reasonable doubt; officer-in-line-of-duty element)	Physical evidence (mask, gloves, duct tape, firearms), footwear impressions, and Dortch DNA plus eyewitness accounts support conviction and show defendants were not police	Eyewitnesses were stressed/inconsistent; four comparison points insufficient; State failed to disprove that defendants were police officers acting in the line of duty	Upheld: evidence sufficient—circumstantial and forensic evidence and victim testimony support convictions; conduct incompatible with being police in line of duty
