Since 2019, I have been trying to find my ex-husband in order to have him served with a Restraining Order. My ex-husband was constantly moving, hiding and avoiding being served. Finally, one day I called a local private investigator and he advised me to call Onyx PI. I had long wondered whether it was feasible to hire a private detective for this case since Metro Dade Police was involved in serving the Restraining Order. As it turned out, David at Onyx did a very important job for me qualitatively and quickly. After speaking with David he agreed to take the case. At 6:30 am the following morning David advised me he had located my ex-husband and sent pictures of his car. He immediately acted, contacting the Metro Dade police who arrived and successfully served my ex-husband the Restraining Order. I am very grateful to David because he did what Metro Dade, Hollywood, Hallandale, North Miami police departments did not, which was locate my Ex. David did it in one day! I advise anyone who needs help to contact David and his team at Onyx PI. Now I live in a world without threats or manipulations from my ex-husband, because yesterday he was finally served. Thank you, David, thank you for your help!
