Charging documents added 1/8/2023: On June 22, 2022, police spoke with the adult female victim who will be referred to as Victim throughout the article.

Victim explained she wished to report several incidents where she was previously assaulted by Walter Crouse Prentiss, III. The victim and Prentiss have resided together at their shared residence in Mechanicsville, MD.

The victim reported the first assault took place on January 17, 2021 at the residence and on this date, victim and Prentiss were engaged in a verbal argument that turned physical due to claims of infidelity, as it was believed Prentiss had been unfaithful in the marriage.

During the argument, the victim stated she attempted to separate herself from Prentiss by remaining upstairs, with him downstairs.

After Prentiss consumed an unknown amount of alcoholic beverages, he confronted her upstairs requesting sexual intercourse, which she refused.

Prentiss followed the victim as she walked into a different room where Prentiss shoved the victim against a wall and began strangling her until she became dizzy, when she was able to escape his grasp and began fleeing, Prentiss grabbed her by the back of her shirt. The victim recalled, and described to the detective she heard a lighter being lit and smelling the distinct smell of burnt hair and realized Prentiss set her hair on fire. The victim was able to extinguish her hair and fled to a bedroom and barricaded herself within the room for her safety.


On February 28, 2021, Prentiss reportedly grabbed the victim by her hair and dragged her into a bedroom where he slammed her head against a wall, and then pinned her against the wall and began strangling her until she was lightheaded.

On May 18, 2021, the victim reported Prentiss raped her. The victim said she arrived home after staying at her sisters house the previous night. She advised she did not recall seeing his vehicle when she arrived home and after a brief amount of time inside she heard Prentiss enter the residence. The victim stated she was fearful of Prentiss as he has previously told her if she came home he would kill her.

The victim stated she ran to a bedroom, locked the door and hid inside the bedroom closest and covered herself with clothing items. As she was hiding, she could hear Prentiss going through the residence looking for her and upon finding the locked bedroom door, he demanded she open/unlock the door. After a short amount of time, Prentiss proceeded to break the door down while damaging the door frame and entered the bedroom where he located her hiding in the closest.

Prentiss grabbed the victim by the hair and dragged her across the room while calling her a names and made claims of her being with other men. Prentiss then pinned the victim to the ground and placed his knee into her stomach and held her down by her shoulders and forced himself upon her and raped her, Prentiss then left the residence where Prentiss was later to claim he would no longer return to the residence if she did not call or report this to the police. The victim suffered injuries from this incident.

On August 19, 2021, the victim reported she was resting in bed watching tv when Prentiss came in and jumped on her, began holding her down and requested sexual intercourse, which she refused. While struggling to get Prentiss off of her, she was struck in the mouth/lip by his elbow causing her to bleed, which Prentiss observed and stopped his assault and all further actions and got off of her and claimed the strike was accidental.

On September 4, 2021, the victim arrived home and before being able to exit her vehicle, Prentiss approached and grabbed her by the hair and dragged her out of the vehicle into the front yard of their residence.

The victim was able to break free and began running towards her vehicle to escape Prentiss who proceeded to throw a glass beer bottle at her which struck her in the ankle and caused her to fall to the ground. She attempted to stand up but was unable to, leading her to believe her ankle was broken, she began crawling away while Prentiss approached and proceeded to grab her and began hitting her head against the concrete while instructing her to get up, which she was unable to do.

The victim sought medical attention where it was discovered she suffered an avulsion fracture to her ankle along with lacerations. She received multiple stiches and a medical boot which had to be worn for approximately 7 weeks.

The last incident was reported to have taken place on October 3, 2021. During this incident the victim and Prentiss were arguing over his drinking of alcohol when he approached her, grabbed her by her tank top straps and ripped the shirt off of her, the victim called a friend during this incident and claimed the friend would call the police, it was at this time Prentiss stopped the assault and fled the residence.

Police made contact with Prentiss on July 22, 2022 via telephone where he was informed that various allegations were made and he was requested to speak in person to discuss the matter. Prentiss explained he would speak with his attorney to set up the possibility of an interview. Contact was then made with his attorney, Hammad Matin P.A., via telephone and was informed his client Walter Prentiss, was alleged to committed several criminal acts. Matin explained he would consult his client and contact the officer later to arrange a time and location to meet.

On July 23, 2022, Matin left a voicemail to the officer explaining his client Prentiss would not be willing to speak regarding any of the alleged incidents.
