Neysi Perez was declared dead after she suffered a heart attack when she heard gunfire near her in the town of La Entrada, in western Honduras.
The 16-year-old was pregnant at the time of her death.
But her boyfriend, Rudy David Gonzales, along with cemetery worker Jesus Villanueva, both claimed to have heard noises coming from her tomb.
Mr Vilanueva told local TV station Primer Impacto: “I heard screams, but I wasn’t sure if they were coming from the tomb or elsewhere.”
The pair then arranged for the concrete tomb to be smashed open with a sledgehammer.
Given new hope that their loved one was alive, the girl’s friends and families prised open the lid of the coffin before fanning and massaging her body in a desperate attempt to revive her.
Neysi's sister Gladys Gutierrez said: "I moved her, she spilled water with blood, she didn't have bad odour, she had normal body temperature."
Her body was rushed to hospital but doctors could not revive her and confirmed she was dead.
While they suggested the noises could have been a figment of the grieving boyfriend’s imagination – there were still things they were unable to explain.
Neysi’s knuckels were scratched and a glass panel at the top of the coffin was broken when it was pulled out of the tomb, leading mourners to believe she had attempted to break through it.
Local media has suggested that the teenager may have suffered a cataplexy attack - a severe form of panic attack brought on by extreme stress, which leads to muscle paralysis and a temporary loss of heart beat.
She was buried once again in her original grave.
