A father grieving over the murder of his son has found a clue that could help catch the killers, KNBC-TV reports.

In November, Kris Meyer’s 27-year-old son, Taylor, was in Playa del Carmen, Mexico. The trip was supposed to celebrate a friend’s birthday, but it turned tragic when Taylor was robbed and fatally stabbed. The perpetrators stole his shoes and wallet and left his body in a park, according to the report.

Police arrested one man but two other people believed to be connected to the crime have yet to be caught.

Kris Meyer was recently in the process of closing out Taylor’s bank account in California when he discovered two transactions on Dec. 7, both of which were at banks located in Oklahoma City.

Meyer told the news station he thinks is son may have been killed soon after he withdrew cash from an ATM.

“The bad guys may have forced him to give up his pin number,” Meyer reportedly said.

Investigators have released surveillance photos of a male and female in a silver SUV at a drive-through ATM using Taylor’s credit card, however it is not immediately clear how those individuals may be tied to the killing.

Meyer said it wasn’t easy looking at the photographs.

“Seeing the person that could potentially, either, he could have been involved in the murder or has connections to the people who were involved in the murder, it gave me a very eerie feeling,” Meyer told KNBC-TV.

He added: “I don’t wish this on anyone, it’s absolutely horrific.”

Meyer said he forgives the people who took his son’s life, but he still wants justice.

“I think it was a cruel thing obviously,” Meyer said. “I would like justice, but I really don’t want anyone else murdered in Mexico.”
