Two arrests were made Tuesday in the August shooting death of a Burlington Northern Santa Fe Railway employee in Tehachapi — his wife and her alleged boyfriend.

Jonathan Michael Hearn, 24, of Hesperia, was arrested Tuesday on suspicion of first-degree murder and conspiracy to commit murder in the death of Robert Limon, 38, the Kern County Sheriff’s Office announced Wednesday.

Sabrina Limon, 35, was arrested on suspicion of first-degree murder, conspiracy to commit murder and being an accessory to murder.

Limon, of Helendale in San Bernardino County, was found dead of gunshot wounds Aug. 17 in a BNSF industrial complex at 1528 Goodrick Drive. Limon had last been seen by coworkers after leaving fieldwork about 5 p.m. to return to the BNSF building.

In August, the BNSF offered a $100,000 reward for information leading to the arrest and conviction to whomever was responsible for the murder.

Throughout the three-month-long investigation, detectives scrutinized hundreds of leads developed through witnesses and information provided by the public, according to a sheriff’s spokesman.

Detectives developed information that Sabrina Limon and Hearn were in a relationship prior to the shooting, authorities said.

Hearn and Sabrina Limon were booked without bail into Kern County Jail and will be appear in court at 3 p.m. Thursday.

City of Redlands spokesman Carl Baker confirmed Hearn is employed as a firefighter-paramedic with the Redlands Fire Department.

According to a 2008 report from the Victorville Daily Press, Hearn was a San Bernardino County Fire Department explorer in Hesperia. While attending Arrow Christian High School, Hearn concurrently attended Victor Valley College, where he received his EMT National registry and graduated from the Firefighter I Academy.

Less than a month after Robert Limon was found shot to death, Sabrina Limon’s Facebook page featured a lengthy remembrance of her husband. The Sept. 8 post thanks friends and family for their “acts of random kindness” and remembers “Rob” as an “AMAZING man ... (who) will never be forgotten.”

“Through this pain and unbelievable tragedy, Rob’s love continues on,” said the post attributed to Sabrina Limon on her page. “God blessed US with Rob for the time he did, and the love he gave was more than some ever will feel or show. I will carry it with me where ever I go, and remind our children of it daily as they grow. It’s a feeling of joy, yet I’m totally numb to the fact that I’m left on earth now without him.”

Sabrina Limon’s Facebook page also shows the couple had a son and a daughter.

A page at the fundraising website GoFundMe featured a memorial fund for the Limon family in the wake of the tragedy, which was apparently set up by a family friend. As of Wednesday, the page was still active and had raised $5,330 from 38 donors in two months.
