A routine evening meal turned tragic in October 2014 when an argument over home-cooked dinner escalated into violence at a San Bernardino residence. Trista Ann Spicer killed her boyfriend, Eric Mercado, during the confrontation and concealed his body in her backyard for nearly eight years. Authorities only uncovered the crime after a tip from a later partner, leading to her recent conviction and imprisonment.[1][2]
The Argument That Ended in Bloodshed
Eric Mercado, 42, expressed dissatisfaction with the beans and meat prepared by his girlfriend, Trista Ann Spicer. Tensions boiled over as he threw the food at her and demanded she sit naked on the couch, a form of control she later described in court. Spicer testified that Mercado then ordered her to fetch coffee, prompting her to grab a cast-iron skillet from the kitchen.[2][3]
She struck him multiple times in the head with the heavy pan before slashing his throat with a kitchen knife or box cutter. Prosecutors argued the attack occurred while Mercado slept on a loveseat, pointing to injuries consistent with an unsuspecting victim. Spicer maintained it was self-defense amid ongoing abuse, including physical beatings and humiliating punishments.[1]
Concealment in a Makeshift Tomb
Immediately after the killing, Spicer enlisted a friend to help wrap Mercado’s body in a deflated air mattress. They hid it in a cramped storage space beneath a concrete staircase in the backyard at her home on the 1400 block of East Davidson Street. A homeless acquaintance later built a brick wall to seal the area, creating what investigators called a makeshift tomb.[1][4]
The remains stayed undisturbed as Spicer continued living at the property. Mercado’s family reported him missing that same month, but leads went cold despite tips over the years. She even told investigators initially that he had simply left after the argument.[5]
Discovery After Years of Silence
The secret unraveled in 2022 when Spicer confided in her new boyfriend, Waylan Gentry, about needing to “get rid” of the body before moving out of state. Her family planned to sell the house, forcing the issue. Gentry recalled her words in court: “She said he was buried under the stairs. I did not believe her.”[5][2]
On August 23, 2022, he contacted San Bernardino police with the tip. Officers searched the property on September 2 and found the decomposing remains behind a sealed doorway in the backyard storage. Spicer faced arrest that day, charged with murder after the grim confirmation.[4]
Trial, Conviction, and Family’s Pain
Spicer’s 2025 trial featured her testimony of abuse and self-defense, but jurors convicted her of second-degree murder in November, along with a deadly weapon enhancement. The autopsy revealed Mercado’s skull shattered in 14 places, with death occurring within seconds from the blows and stab wound. Three former acquaintances of Mercado testified to his volatile nature, yet the jury rejected her claims.[1]
At the March 27, 2026, sentencing in San Bernardino Justice Center, victims’ family members delivered emotional statements. Eric’s sister, Mahira Torres, told Spicer, “You took my brother’s life, and you shattered ours.” His mother, Guadalupe Plascencia, added through a victim advocate, “I can just tell you that I really feel pity for you. You will never be able to understand the enormous pain that you have caused.”[4][1]
