Woman Helps Catch Her Father’s Alleged Killer Using

By Michael Klazema on 6/14/2013

Thanks to the resources offered through, one woman’s quest to see her father’s alleged killer behind bars has come to an end.

Joselyn Martinez was just 9 years old when an assailant shot her father to death in 1986 outside the family’s restaurant. At the time, New York police were able to identify the shooter as Justo Santos, but they were not able to arrest or prosecute him. They believed that Santos had fled the country.

While the police ended their investigation, Joselyn Martinez never gave up on finding her father’s killer. About 8 years ago, the aspiring actress began working the cold case in earnest, using internet search tools such as those available from at that time. She made finding Justo Santos her business, and even went so far as to register as private investigator so that she could use business-oriented tools from companies like offers a variety of background check tools, including products like US OneSEARCH, which can compare a name against a database of over 450 million records taken from state and local law enforcement databases across the country. Even using an alias isn’t enough to allow an individual to hide from, because also offers a tool called US AliasSEARCH, which enables individuals to conduct searches based on a Social Security Number. While these tools are most commonly used by employers looking to evaluate job seekers’ suitability for various positions, they can also be used by investigators like Joselyn.

For 8 long years, Joselyn kept an eye out for mentions of Justo Santos on the internet, hoping that her online searches would uncover some mention of the man who had allegedly changed her life so dramatically back in 1986.

Then, one day Joselyn was shocked to open up a background check report and realized she was looking right at records belonging to the man accused of killing her father. She had already convinced the police to reopen the case, so she was able to immediately hand over the information she had found on Santos to the police.

Armed with the Miami address and phone number that Joselyn had given them, the police sprang into action. Working with local law enforcement in Miami, police arrested Santos on June 6. Santos reportedly confessed to the murder of Joselyn’s father, Jose Martinez, at the time of his arrest. He appeared in court in Miami on June 11 and will be extradited back to New York, where he will face murder charges.

New York Police Commissioner Ray Kelly was happy to give Joselyn the credit for solving the case. He applauded her determination and resolve in dedicating her own time and resources to the effort to find her father’s killer, and said that police appreciated the information her investigations uncovered.

Joselyn said that she hopes seeing Santos behind bars will finally allow her family to feel at peace about the situation. "We know it's not going to bring the person back, but this is for my dad," Joselyn said.
