Go to the police station, Juan, and explain your situation to them.
File a complaint by visiting the police department in person. Ask to speak with a police officer and make sure you bring any relevant evidence with you to this meeting, including any relevant photos, text messages, etc. If you have physical evidence at home that cannot be transported and is best seen in person, you might consider contacting the police department to have an officer visit your home instead of going to the police department in person.
