The first 48 hours after a felony arrest in Bexar County: What to do and what not to do

An arrest upends everything. Phone calls stop, hours blur, and every decision feels urgent. In Bexar County, the first 48 hours are often the difference between a controlled defense and a case that hardens before you can respond.

If you or a loved one has been detained in San Antonio, you need a precise plan. This guide explains what to do, what not to do, and how fast action can preserve rights, leverage, and options. The best time to hire a lawyer was yesterday; the second best time is now.

Del Prado Law is led by Mario Del Prado, a Board-Certified Criminal Law Specialist with more than 35 years of trial experience in Texas courts and prior leadership service as Chief of the Criminal Trial and Major Crimes Divisions at the Bexar County District Attorney’s Office. When your freedom is on the line, experience and speed matter.

The first five moves within hours of arrest

1. Identify yourself, then stop talking. Provide your legal name and basic identifying information when required. Then say, I am invoking my right to remain silent and I want a lawyer. Do not answer questions about where you were, who you were with, or what happened. Do not try to explain or outsmart the process.
2. Do not consent to searches. If officers ask to search your vehicle, home, phone, or clothing, clearly say, I do not consent to any searches. If a warrant is presented, do not interfere. Simply state your lack of consent and contact counsel.
3. Call a lawyer before anyone else who is not family. If you are deciding who to speak to first, the answer is a lawyer, not the police. Even if you believe you can clear things up, your words can be misinterpreted or taken out of context. Ask for counsel and wait.
4. Secure evidence now. Time-sensitive records often decide close cases. Have a trusted family member start preservation requests immediately for 911 audio, police body-worn camera, dashcam, nearby business surveillance, Ring or Nest video, and scene photos.
5. Control communications. Do not call accusers, witnesses, or investigators. Do not post online. Do not text about the incident. Anything you say or type can be used against you.

If you need immediate legal guidance, speak with a criminal defense attorney in San Antonio who can intervene at once. Del Prado Law can coordinate preservation and protect your rights from the start.

What a defense lawyer does in the first 48 hours

An experienced criminal defense lawyer uses the opening days to set the tone, protect rights, and shape the record that courts and prosecutors will later rely on. Typical early steps include:

• Contacting Bexar County authorities about custody status, booking, bond eligibility, and holds or detainers.
• Demanding preservation of 911 calls, dispatch logs, bodycam and dashcam footage, jail calls, and nearby surveillance.
• Securing witness names, phone numbers, and short statements before memories fade.
• Assessing search-and-seizure issues, traffic stop legality, warrant sufficiency, and detention timelines.
• Preparing for a magistrate appearance, bond arguments, and early conditions.
• Preventing harmful interviews or consent searches that undermine later suppression motions.
• Distinguishing between state and federal exposure and advising accordingly.

Early intervention often preserves options that disappear quickly, particularly in cases involving digital data and third-party video. If your case may involve federal triggers, ask for a federal criminal defense attorney who knows the Western District of Texas procedures and the United States Attorney’s Office practices. Del Prado Law handles serious state and federal matters and can move fast to protect you.

Bexar County basics: identification, magistrate, and bond

After arrest in San Antonio, you are processed and taken before a magistrate for probable cause and bond consideration. Provide identification when asked, but do not discuss the facts. Your lawyer can argue for conditions that get you home and protect your job and family obligations.

Families can help by organizing paperwork for bond and early hearings. Gather:

• Booking number, location of custody, and any court notices
• Government ID, proof of residence, employment, and community ties
• Names and contact information for potential witnesses
• Medical or mental health information relevant to conditions or mitigation

Bring this material to your first meeting with counsel so your defense can start on solid ground.

State vs. federal triggers you should know

Not every San Antonio arrest stays in state court. Certain facts can draw federal interest, including multi-county or interstate conduct, alleged use of firearms during drug trafficking, large-scale narcotics distribution, or digital evidence that crosses state lines. Federal cases move faster and rely on grand jury indictments, detailed agent reports, and strict detention standards. If you suspect federal involvement, ask for immediate federal defense guidance before speaking to any investigator.

Consent, searches, and the risk to suppression motions

Suppression motions attack illegally obtained evidence. They work best when your rights were clearly invoked and not waived. Common pitfalls in the first 48 hours include:

• Consenting to a search of a phone, car, or home because you feel pressured or want to appear cooperative.
• Volunteering location histories, passcodes, or cloud access.
• Chatting with officers while waiting for paperwork, even after invoking silence.
• Posting or messaging about the event, creating a new government exhibit.

Strong suppression arguments often hinge on clean invocations of rights and prompt objections to consent. If an officer asks for permission, say no and ask for your lawyer.

Evidence families should preserve immediately

Time is your opponent. Families should take these steps while counsel coordinates formal preservation:

• Request 911 audio and CAD/dispatch logs from the San Antonio Police Department or the Bexar County Sheriff’s Office as soon as you learn there was a call.
• Ask nearby businesses and neighbors to save surveillance or doorbell camera video for the hours around the incident.
• Save texts, voicemails, social media messages, location data, health or fitness app records, and rideshare receipts that show timelines.
• Photograph injuries, the scene, clothing, and weather or lighting conditions the same day if possible.

Coordinate with counsel before contacting anyone connected to the accusation. Your lawyer will manage these communications to avoid misunderstandings.

A 10-item checklist for the first 48 hours

• Say your full name and basic identifiers, then invoke silence and ask for a lawyer.
• Decline consent to all searches of your person, home, vehicle, and devices.
• Call a lawyer first, not the police, not the accuser, and not social media.
• Share the booking number and location with your family.
• Preserve 911, bodycam, dashcam, and nearby surveillance video.
• Collect witness names, numbers, and brief neutral notes.
• Gather ID, proof of address, employment verification, and bond co-signer information.
• Save phone records, photos, messages, and location data relevant to the timeline.
• Avoid all jail calls about case facts; assume they are recorded.
• Meet counsel with all paperwork and a written timeline.

FAQs for San Antonio arrests

• Should I hire a criminal defense attorney right after an arrest?
• Yes. Early counsel often preserves evidence, prevents harmful statements, and positions you for better bond and case outcomes. Waiting usually narrows options. The best time to hire a lawyer was yesterday; the second best time is now.
• What does a criminal defense attorney do in the first 48 hours?
• Counsel intervenes with law enforcement and the jail, preserves 911 and video evidence, shields you from interviews, evaluates search-and-seizure issues, prepares for bond, and begins building suppression and defense strategies.
• What evidence should my family preserve immediately?
• 911 audio, dispatch logs, bodycam and dashcam footage, nearby surveillance, doorbell videos, photos of injuries or the scene, texts and messages, location and app data, and names of witnesses.
• Do I have to consent to a search after I am detained?
• No. You can refuse consent. Say, I do not consent to any searches. If officers have a warrant, do not interfere, but do not assist. Contact your lawyer.
• Who should I talk to first, the police or a lawyer?
• A lawyer. Speak with counsel before any conversation with investigators or prosecutors, whether state or federal.
