Private Investigations

Domestic Violence Investigations Conducting a private investigation for domestic violence allows the victim of abuses to gather adequate legal evidence to prosecute. This evidence can give hesitant victims the confidence to press charges and leave a negative situation. This evidence can be gathered through witnesses statements, email discovery, and social media evidence.

Elder Abuse Investigations Elder abuse can be emotional, physical, or mental and can include negligence or failure to provide assistance. Often the victim of elder abuse is unable or afraid to press charges due to threats or being unaware of the punishable offense. SJ Investigative Services, LLC will gather evidence through witness statements, and using investigative methods necessary, to ensure your love one is safe.

Child Custody Investigations Divorce proceedings can be very stressful, and child custody is often the center of interest for both parties. As the court is focused on the child’s best interests, gathering evidence about negligence, abuse, or inhospitable situations are necessary in ensuring your child has the best situation possible. SJ Investigative Services, LLC will acquire information and evidence you need for court and in the best interest of your case.

Process Service

In addition to providing private investigations for these family law cases, we will serve due process as necessary. By running thorough diligence searches, we locate the defendant who is attempting to evade service and serve them legally according to the law. Our process servers are experienced with Washington D.C. and the surrounding areas, and through our extensive network of associations, we will find you a process server anywhere within the U.S.

Court Record Searches

We also search local, state, and nationwide courts for criminal and civil documents and records needed for litigation or other court cases. Our office can also acquire background information used to check the criminal history of a potential employee, nanny, or potential business partner.


For those attorneys who need a competent investigator, I am recommending Sharon Jenkins, I have been working with Investigator Jenkins for many months now, and I have always found her work to be exceptional. In each situation presented to her, Investigator Jenkins took the ball and made things happen. - Kevin S. Kassees Attorney at Law

Ms. Jenkins has performed at least one outstanding example of her ability as a process server. She located (against what I consider against all odds) a defendant/"drifter" whose whereabouts had been unknown for at least two years) served her by waiting up all night with a very narrow window of opportunity, filed her affidavit in court and immediately informed me all of this less than a week! Her work allowed me to gain for my client, the father of two very young girls, their permanent custody which doubtless improved their lives of the children as well as that of their father. - Richard H. Speidel Attorney at Law

I have used the investigative services of Sharon Jenkins in neglect and abuse (family) cases in the District of Columbia. I have found Ms. Jenkins to be prompt in completing the service of process and both timely and accurate in the filing of required affidavits with the court. - Cynthia Nordone Attorney at Law

Ms. Jenkins performed an investigation for me dealing with trademark infringement. I was alerted to a business in Washington DC that may have been using our company trademarks. Since I am here in California. I needed to find a local investigator that could visit the business and take photos for me so we could in fact verify if there was a potential trademark issue.

If ever in need of an investigator in the area. I would definitely seek out her professional services again and would highly recommend her to anyone in need. - Rachael Blake Paralegal
