Crime Scene Analysis and Suspect Background

Incident Timeline:
- Robert Stange, manager at Sigmor convenience store, and Pete Gonzalez were instructed by police to remain outside after incident.
- Stange had worked the morning shift, joking with Wanda Lopez before leaving her responsibility at 3 PM on Valentine's Day.
- Stange received a call hours later, finding Wanda injured and the scene chaotic upon arrival.

Outside the Store:
- Blood was clearly visible both outside the store and through the windows, indicating a severe situation.
- Police presence suggested an ongoing investigation into a possible capital murder.
Inside the Store:
- Stange observed a disturbing scene of blood smeared and pooled across the floor, a trail leading from the clerk’s counter, which had a lift-top and flap door that were found open, indicating forced access.
- Wanda Lopez's bloody footprints were prominent, suggesting she had attempted to escape or seek help before being overpowered.

Robbery Response Plan:
- Sigmor had protocols emphasizing cooperation: employees were trained to hand over cash to minimize risk.
- Stange had rehearsed this response with Wanda, who had shown no inclination towards violence during robberies.
- Cash drawer was limited to $75, with significant precautions against keeping large sums of money visible.

Initial Scene Observations:
- Detective Olivia Escobedo and photographer were initially the only investigators in the store, leading to a swift but seemingly incomplete apprehension of the situation.
- A substantial quantity of blood, evidence of struggle, and cash left behind made it evident this was beyond a simple robbery.
Forensic Details Noted:
- A knife was later discovered, adding complexity to the perspective of the crime as merely theft.
- Observation of Wanda's struggle indicated a confrontation that escalated beyond a robbery scenario.

Carlos DeLuna's Personal History:
- Arrested shortly after the crime; his mother was to be a key witness but was seriously ill during the trial.
- As a child, DeLuna exhibited behaviors aligned with learning difficulties; family members noted that he was slower than his peers.
- Early involvement in minor crimes escalated through his teenage years, leading to repetitive encounters with law enforcement.
Family Dynamics:
- DeLuna's mother, Margarita, displayed significant affection towards him, in contrast to the harsher treatment of his siblings.
- His upbringing featured instability, with various familial and logistical challenges impacting all children in the household.

Miscommunication and Oversight:
- Stange felt excluded from critical discussions during the investigation, indicating a lack of engagement with store management in assessing robbery-related motives.
- Speculation around potential personal motives emerged but were reportedly overlooked by investigating officers, resulting in unresolved conclusions about the nature of Wanda’s murder.
Arrest and Public Perception:
- DeLuna's arrest was exacerbated by both his prior police encounters and his family's socio-economic background, framing him in a particular light.
- Despite presented evidence not supporting theft, he was implicated based on existing biases and assumptions from prior interactions with police.
