A $10,000 reward is now being offered for information on a double-killing in Mammoth that happened in January 2017.
On January 31, deputies were called to assist the Mammoth Police Department in the 400 block of South Main Street after police responded to a call of shots fired.
Mark Reynoso, 34, and Maria Desantiago, 28, were found dead with apparent gunshot wounds.
Since the couple was found shot and killed just feet from their home, $5000 was being offered for information.
Now, Mark's parents, Joe and Lanie Reynoso have doubled that reward in hopes of finally getting some answers.
The Pinal County Sheriff's Office says Reynoso was awaiting trial for manslaughter charged tied to a deadly crash in 2015.
The Sheriff's Office did not want to comment on Friday about the murder investigation.
As the second anniversary of Mark and Maria's death looms, the Reynoso's are pleading for anyone with information to come forward.
Anyone with information is urged to contact 9-1-1 or the Pinal County Sheriff’s Office or Silent Witness at 480-Witness.
