Video Summary — “Love Triangle Murder in Longmont, Colorado” 🔪📮

Hosts

Johnny Mitchell & Matthew “Chainsaw” Cox — commentary throughout, frequent humor and opinionated reactions.

Victim: Jason Schaefer, 33, USPS postal carrier and single father of a 5-year-old.
Perpetrators: Devon (Deon) Shriner, 26 (postal worker & mother of victim’s child) — shooter; Andrew “AJ” Richie, 34 (federal correctional officer) — accomplice/getaway planner.
Date/Place: October 2021, Longmont, Colorado (suburban neighborhood).
Incident: Mail carrier shot multiple times in broad daylight while on route; died at hospital.

Surveillance (doorbell/Nest, neighborhood CCTV) captured shooter approaching calmly and firing; footage later matched to clothing/photos.
Phone/GPS/Scanner data:
- Devon’s postal scanner/GPS tracked and showed suspicious gaps/locations inconsistent with her stated route activity.
- AJ’s phone/location data placed him in the Longmont area and following/monitoring the route.
Text messages/photos:
- Devon sent AJ a photo of herself wearing the same hoodie/outfit later seen on the shooter.
- Messaging history revealed months-long violent talk; AJ encouraged violent solutions and discussed killing targets.
Witnesses & neighbors provided footage and sightings that matched timeline.
Police tactic: officers retrieved the victim’s child from daycare and brought him to the station to compel Devon to come in — she arrived to pick him up and was interviewed.

Devon initially denied involvement; invoked right to counsel during interrogation.
AJ initially claimed he tried to dissuade Devon and even warned Jason; investigators found his timeline contradicted by phone/GPS and surveillance.
Both attempted alibis/cover stories that failed once cross-checked with digital evidence.

Both Devon and AJ charged with first-degree murder; AJ prosecuted under Colorado’s complicity law (same charge despite not firing the weapon).
Convictions:
- Devon found guilty (March 2023) — sentenced to life without parole.
- AJ later convicted (six months after Devon) — also received life (per video narration).

Underlying motive: jealous/volatile love triangle and custody dispute — Devon had recently been served custody papers; tension with Jason over child and relationships.
AJ’s motive/role: intimate involvement with Devon, encouragement of violence, active assistance (scouting/tracking the route) rather than mere deterrence.

Hosts repeatedly criticize suburban culture and Colorado; use dark humor and strong language.
Emphasis on how modern surveillance (doorbell cams, CCTV, phone data) made detection and conviction straightforward.
Discussion of federal employees implicated (postal worker, federal correctional officer) and commentary on law enforcement/federal system.
Ethical/technical notes: hosts debate police tactic of bringing child to station; discuss legality/strategy of interrogation and Miranda/involvement of federal agents (USPS inspectors).

Multiple corroborating digital sources: doorbell/CCTV footage, photos/texts, phone/GPS and postal scanner logs.
Witness video and neighbor reports.
Incriminating messages/photos between co-conspirators.
Apprehension strategy that brought suspect to investigators (child at station).

Modern surveillance ecosystems make brazen daytime crimes highly traceable.
Coordinated digital evidence (phone, GPS, CCTV, messages) is decisive in reconstructing events and disproving alibis.
Complicity laws can hold non-shooters equally accountable when they plan or assist a murder.
Emotional motives (custody battles, romantic jealousy) often underlie violent conspiracies.
