During the 2019 calendar year the Cecil County Sheriff’s Office Criminal Investigation Division has been comprised of eight Detectives, one Sergeant and one Corporal. One of the eight Detectives was primarily assigned to the Child Advocacy Center. Two Detectives were assigned to the Megan’s Law Unit and were responsible for monitoring registered sex offenders in Cecil County. The remaining five Detectives were classified as “general” Detectives and were assigned various cases to include, but not limited to, burglary, robbery, financial crimes and death investigations.

In 2019 a Detective from the Criminal Investigation Division continued to administer and monitor RAPIDS (Regional Automated Property Information Database) for Cecil County to ensure locally operated pawn shops comply with county ordinances.

Throughout the year the Criminal Investigation Division received 465 referrals from the Department of Social Services and initiated over 100 cases that were jointly investigated with the Department of Social Services.  These cases include Child Sexual Abuse, Child Physical Abuse, Child Neglect and Child Fatality investigations.

In 2019 Detectives authored and executed over 90 search warrants. This includes but is not limited to warrants for residences, vehicles, DNA, cellular phones and other electronic devices.

Members of the Criminal Investigation Division have continued to attend trainings to increase their knowledge in multiple areas to include; homicide investigations, human trafficking and interview and interrogation techniques. Additionally, a Detective attended a one week long Cellbrite training where he is now certified to forensically extract data from cellular phones and other electronic devices.
