HILL CITY — Authorities confirmed late this morning they located a person of interest in a double homicide Thursday in Graham County.
Law enforcement officials were looking for Efren Lloyd Mascarenas, 29, who was described as 5 feet, 2 inches tall and weighing 130 pounds with brown eyes and black hair. Through the night, he was believed to be armed and dangerous.
Mascarenas was located at approximately 9:45 a.m. today. The Phillips County Sheriff’s Office, on its Facebook page, said he was “located and no longer a threat.”
The homicides were discovered Thursday afternoon after a Graham County dispatcher received a 911 call about an unresponsive male in a rural area of the county, according to a release from the Graham County Sheriff’s Office.
When EMS and officers arrived, it was apparent a double homicide had occurred, the release said. The sheriff’s office, Hill City Police and Kansas Bureau of Investigation began the investigation.
The names of the victims have not yet been released.
A vehicle Mascarenas was known to be driving, a blue 2005 Dodge Charger, was found early in the evening.
Law enforcement personnel established a search perimeter around the area where the vehicle was located Thursday evening in a ditch on a road in rural Graham County.
Residents in northeast Graham, southeast Norton, southwest Phillips and northwest Rooks counties were advised to secure their property and remain inside.
Through the evening and into early Friday morning, with temperatures dropping into the low 20s, personnel from the Rooks and Graham county sheriffs officers were joined by law enforcement from seven different agencies, including the Graham, Phillips, Norton and Ellis County sheriff’s offices, Hill City and Hays police departments and KBI.
Through the night into the early hours of Friday, officers on foot searched with night vision equipment and K9 units, at times entering buildings on farmsteads. Air patrols from the KHP searched over areas that ranged from near Bogue in Graham County to Logan in Phillips County.
Mascarenas, who also has an alias of Efren Lloyd Mascarenas Jr., according to the Kansas Department of Corrections, has been in and out of state prisons in the past.
He has three convictions in Ellis County — two for aggravated battery — and one in Trego County for aggravated battery. The convictions in Ellis County date back to 2010.
Mascarenas has spent time in correctional facilities in El Dorado and Lansing, and had been issued numerous disciplinary reports at the two facilities — including battery, fighting, dangerous contraband and assault.
