A

Maryland man who pleaded guilty on Tuesday to prostitution charges kept

detailed “meeting minutes” and a “comptroller’s report” that allowed

investigators to document his illegal business, according to court records.

Investigators also found a

self-described prostitution “training manual” and contracts with victims when they

searched the Laurel home that Robert Carl Diienno, 32, shared with at least

three women who worked as prostitutes for him, according to a court filing

accompanying his guilty plea in federal court.

He pleaded guilty to three

prostitution counts that each carry a maximum sentence of 20 years in prison.

Diienno was arrested in

June 2017 after Laurel police officers responded to a report of a disturbance

at his home and found two women hiding in a wooded area nearby. One of the

women told police that Diienno had assaulted her over an argument about

prostitution.

The “meeting minutes” that

investigators found in the home recorded the attendance of Diienno’s meeting

with prostitutes and included a report on potential new recruits, the court

filing says. A “comptroller’s report” documented his victims’ weekly earnings,

according to the filing.

The contracts with his

victims said they must agree to “accept any punishment the Pimp decides to

inflict, whether earned or not,” the filing says.

The women gave Diienno the

proceeds of their prostitution activities, which included travel from Maryland

to Washington, DC, Virginia, Florida and South Carolina, according to

prosecutors.

US District Judge George

Jarrod Hazel is scheduled to sentence Diienno on December 8.
