4064639247?profile=originalIn the beginning stages of a horrible events that unfolded in December of 2015, Private Detective Barry Donadio was on the case for the Reyes Family.

Barry Donadio is a former member of the U.S. Secret Service that now uses his expertise in the private sector under is private firm Public Security LLC. He was first licensed as a Private Investigator in New York State in 2001. Since then, he obtained Private Detective Agency licensing in the State of Maryland.With both licenses, he performs executive protection, private security, private investigation, military strategy and anti-terrorism consultation.


Barry Donadio's involvement in the case is only now being revealed after more than two years later because of Donadio's policy of strict confidentiality and his client had granted permission to make the information public.

Shortly after the fatal assault on Douglas Reyes, an undisclosed member of the Prince George's County Latino community that is close to the Reyes family, asked Mr. Donadio for help.

Mr. Donadio immediately met with the Reyes family and offered full support. It was a very short period of time before the local Police made an arrest of a suspect prior to Donadio beginning his private investigation.


Donadio remained with the Reyes family and also provided executive protection for the them during the massive funeral services for their loved one.

In July of 2017, Donadio's Detective Agency got attention when it searched for a missing Kent Island girl that later was reunited with her family.
