The members of the Accident Investigation Unit are specially trained in the physics and forensics of vehicular accidents. Some are reconstruction experts, and are able to completely reconstruct the conditions at the time of the accident. Working with the Crime Scene Photographers, these deputies produce court-ready data books that concisely detail each accident they investigate. Like the Mounted Patrol, this is a volunteer unit, made up of regular deputies who perform these tasks in addition to their normal duties.

The deputies currently assigned to bike patrol responsibilities operate as highly visible and mobile units that can respond to special terrain or area problems that are inaccessible to standard patrol vehicles. These units are widely accepted and welcomed by area residents and frequent the jogging and bike trails that have been a haven for mischief and criminal activity in the past. The bikes are specially designed for patrol activities and personnel have been trained in the tactical use of the bikes for these type of specialized operations

Constable Ron Hickman has established the Harris County Clean Air Task Force for the purpose of enforcing state laws, codes, rules and regulations pertaining to improper vehicle emissions and the sale or distribution of counterfeit vehicle inspection certificates. This Task force will help crack down on fraudulent, fictitious or improperly issued automotive state inspection certifications. Vehicles that circumvent the emission laws contribute to health threatening pollution and many of the vehicles are accidents waiting to happen due to faulty brakes, bald tires or some other safety hazards. The State vehicle inspection program is designed to help keep vehicles safe to operate as well as to help reduce air pollution. Our program, which is supplanted by grant funding, consists of a two part effort. Task Force investigators will work behind the scenes to reduce the number of fraudulent, fictitious or improperly issued automotive state emission inspection certificates.

The deputies who make up the Crime Scene Photography Unit are trained in all aspects of crime scene photography and videography, including night and low light photography. They respond to any major crime scene and supplement the investigating officer's report with photographs. Some have also extended thier expertise into other types of evidence collection and documentation. This is also a volunteer unit, made up of regular deputies who perform these tasks in addition to their normal duties.

The Domestic Violence Unit is a specialized division which falls under Victim's Assistance, and has similar duties. Whereas the Victims Assistance deals with the victims of all crimes after the fact, the Domestic Violence Unit targets domestic violence incidents and will respond to those calls in progress. This allows them to conduct an on-the-scene evaluation of the situation and to assist the complainant in the filing of protective orders, charges and compensation claims as needed. They also offer referral to resources within the community.

Due to the alarming frequency in Harris County, family violence is the number one cause of injury to women. No one should have to endure family violence. No one. Ever. Period. But unfortunately it does–and when it does, there is help. The Harris County Pct. 4 Constable's Office, Victim Assistance/Family Violence Unit was established in 1994 to combat this problem.

Maybe you have first hand experience as a victim of domestic violence, maybe you have a friend, co-worker or neighbor who is being abused right now. Who ever you are, where ever you are, we want you to know that you do not have to put up with the abuse and you are capable of living a life free of violence.

Our goal is to intervene where violence has occurred by placing a priority on victims' safety and promoting a community wide response to reduce violence against women. The Constable's Department approaches these concerns in several different ways. First, with the criminal justice system by making lawful arrests of batterers. Secondly, with the victim by providing an immediate response and crisis intervention with emotional support, counseling referrals, and alternatives to the violence. Thirdly, in the community with public awareness and education in the prevention of family violence. Family Violence is a criminal offense and prosecuted like any other violent crime!

Our liaisons, trained in direct on-scene contact and victimization, assist victims of violent crimes and domestic abuse by directing victims through the compensation application process, intervening on behalf of the victim and their families to employers, and by keeping them informed of the status of the investigation and legal process. They also refer clients to counselors specifically trained in these services and intercede with health care providers. They strive to return the victim to a pre-incident level of functionality and reduce the overall impact of the incident on the victim and their family. Their secondary goal is to increase educational awareness that results in enhanced concern for the areas of victimization.

As a victim of a crime, you may experiencing psychological and emotional trauma. The Harris County Precinct 4 Victim Assistance Program is committed to restoring the respect and dignity of crime victims through crisis intervention, counseling, advocacy, education, information and referral. Every effort will be made to provides services to individuals who request assistance from law enforcement.

Addressing the needs of a victim will in turn facilitate the victim's' and witness's' willingness and ability to cooperate with the Criminal Justice System in the investigation and prosecution of the crimes.

Special consideration is also directed to law enforcement officers and the community in educating them in the victimization process and recognizing the needs and rights of crime victims.

Precinct 4 has personnel and equipment dedicated to high water rescue in the event of flooding such as that which occurred during Tropical Storm Allison.  Located at the High Water Rescue and Command Center facility are a "deuce and half" military style transport truck capable of navigating high water for rescue purposes.  Also located there is 21 foot center console outboard motorboat.  The Deputies assigned to operate this equipment have received special training from the U.S. Coast Guard to better prepare them to perform rescue services.
