Gabe Alcon, 22, one of four people wanted for questioning in connection with the murder and who police believe was the man who likely shot Jacquez in the car, was arrested Tuesday night. He was found hiding behind a car in the vicinity of a Bloomfield home, Sheriff's Lt. Cory Tanner said in a prepared statement.
Jacquez was found dead May 27 by a mountain biker in a remote area about two miles north of NM 516. An autopsy revealed he was shot five times in the back of the head at close range.
Alcon was charged with third-degree felony tampering with evidence and fourth-degree felony conspiracy to commit tampering with evidence. He has not yet been charged with the murder.
"Based on the learned information, additional charges will be filed for Alcon's role in the homicide," Tanner said.
The search for 20-year-old Richard Winters, 29-year-old Vincent Montoya and 26-year-old Sarah Martinez continues.
Investigators believe Jacquez was shot while inside the car and his body dumped in the remote area. Except for his boxer shorts and white socks, all of Jacquez's clothing was removed.
According to court records, several people, including Montoya, Martinez, Winters and Alcon, allegedly dismantled the vehicle and attempted to burn the interior along with their clothing as a means to destroy evidence.
Investigators located the fire pit and recovered several items of clothing that matched descriptions of what Jacquez and Alcon were believed to be wearing the night of the shooting.
Tires also were found that matched tread marks at the location where Jacquez's body was found, according to police records.
Detectives "still are investigating the motives behind the shooting," Sheriff's Sgt. Daniel Clugston said. "We still are working on locating people and working leads."
Deputies responded about 8 p.m. Tuesday to the Bloomfield home after hearing reports that Jacquez's brother was at the house and attempting to force his way in, threatening bodily harm if he located Alcon.
Alcon was arrested without incident.
He also was charged with aggravated assault against a household member, shooting at a dwelling and criminal damage to property, all fourth-degree felonies for a May 19 incident in which he was accused of firing a weapon into the home where his girlfriend was standing on the porch.
The investigation continues. Anyone with any information is asked to contact the San Juan County Sheriff's Office at 505-334-6107.
