Farmington assault suspect arrested on felony aggravated battery warrant

A Farmington man already on probation for drug-related crimes was booked April 15 into the San Juan County Adult Detention Center on a warrant for third-degree felony aggravated battery causing great bodily harm, a charge that carries a basic sentence of three years in prison under New Mexico law. Johnathan Timothy Lamy, 33, now faces a preliminary examination on April 29 in Farmington Magistrate Court, the next step that will determine whether prosecutors have enough evidence to move the case forward.

The warrant ties back to an alleged assault near Orchard Plaza in Farmington on Sept. 24, 2025, when investigators say Symantha Leigh Sam was left in critical condition after a severe beating. The affidavit describes serious head trauma and other injuries, including a fractured temporal bone, a fractured parietal bone, subdural bleeding between the brain and skull, and an injured hand. Sam reportedly told police that Lamy, whom she knew by the nickname JP, kicked her in the head and left thigh after accusing her of taking his property.

Farmington Police had previously posted a missing-person notice for Sam, adding another layer to a case that stretched for months before Lamy’s arrest. Sam’s detention-center record lists a Farmington address and a date of birth of Nov. 4, 2000. Lamy’s booking record lists a Farmington address and a date of birth of Aug. 12, 1992. Records from the detention center also show Lamy had a prior booking and release in January 2026 on unrelated matters, while Sam’s record shows a Jan. 26, 2026 booking with a hold pending matters.

The criminal history tied to Lamy reaches back more than a decade, with earlier battery and drug-related convictions and a charge involving unlawful carrying a deadly weapon. That background gives prosecutors and judges more to weigh as the case moves through the court system, especially when they decide detention, release conditions and the risk of future violence.

Under New Mexico statute 30-3-5, aggravated battery that inflicts great bodily harm is a third-degree felony. In practical terms, that classification is what pushes the case beyond misdemeanor handling and into the felony track in the Eleventh Judicial District, where Farmington Magistrate Court serves as the first gatekeeper before a case can advance toward district court. For San Juan County, the April 29 hearing will show whether this long-running assault case stays alive in court or stalls at the preliminary stage.
