A Colorado man arrested this week in Cheyenne faces two felony counts after an early‑June assault that left a local resident hospitalized and briefly unconscious. The case moves into the Laramie County court system today as prosecutors prepare for a preliminary hearing later this month that will determine whether the matter goes to trial.
David Fulmer, born in 1983, was taken into custody following an investigation by the Laramie County Sheriff’s Office. Authorities say he is accused of aggravated assault and robbery resulting in bodily injury — both felonies that carry significant prison time and fines if a jury convicts him.
Alleged attack and injuries
Deputies tied Fulmer to an incident that occurred in the early hours of June 6, when a Cheyenne man was found badly injured near a residential intersection. The victim was transported to Cheyenne Regional Medical Center with head trauma, a concussion, a facial fracture near the eye socket and a gaping cut to his lip.

According to law enforcement accounts, the victim awakened outside his home after being struck and left at the scene shortly after 2 a.m. Investigators say cash and personal items were taken during the encounter.
What investigators say happened
Prosecutors’ narrative traces the evening back to Fort Collins, where the victim had been earlier with his wife. After a reported argument, the victim withdrew money and bought marijuana, then was picked up by a female acquaintance and three men, one of whom is identified as Fulmer.
The group drove back to Cheyenne and stopped near the victim’s neighborhood. Surveillance footage from nearby residences — and items recovered at the scene — are central to the sheriff’s office case. A cellphone found close to the scene was later linked to Fulmer, officials say.
- Surveillance video: Shows a vehicle arriving at the intersection shortly before 2 a.m., voices and a car horn, and doors opening as the vehicle pulls away.
- Physical evidence: Personal effects found at the scene, including a phone traced to a suspect.
- Victim statement: Reports being struck while reaching into the car, then hit with an object, robbed and dragged from the vehicle before falling and hitting his head.
- Text messages and interviews: Messages between the female passenger and the victim’s wife, plus differing witness accounts, describe an escalating confrontation and disputes about who struck first.
Prior convictions and possible impact
Police records and court files reviewed by investigators indicate Fulmer has prior convictions dating to the mid‑2000s and later, including offenses prosecuted in California and Colorado. Those prior records are likely to be part of pretrial considerations but will not be proved to a jury unless introduced according to court rules.
Charges, custody status and next steps
Fulmer faces two felony counts: aggravated assault and battery, and robbery causing bodily injury. Each charge carries a maximum statutory sentence of up to 10 years in prison and fines that can reach $10,000. He was arrested during the weekend of July 18 and is currently being held without bond, authorities said.
| Date | Event |
|---|---|
| June 5–6, 2025 | Alleged confrontation and assault in Cheyenne; victim hospitalized |
| July 18, 2025 (weekend) | Fulmer arrested and booked; held without bond |
| July 30, 2025 | Preliminary hearing to determine if felony charges will proceed to trial |
The preliminary hearing scheduled for July 30 will test whether prosecutors have enough admissible evidence to take the case before a jury. If the court finds probable cause, the matter will move forward to arraignment and, potentially, trial.
For the victim and his family, the upcoming hearing is the next formal step in a case that has drawn local law enforcement resources and scrutiny. Prosecutors and defense attorneys will use the intervening weeks to prepare, including reviewing surveillance footage, witness statements and medical records that describe the extent of the injuries.
