An 18-year-old Marietta man is being held without bond at the Cobb County Adult Detention Center after investigators say a young girl described being physically restrained and forced into sexual acts during a summer 2025 encounter. Shawn Aiden Marshman was arrested on August 27 and now faces felony charges of rape and aggravated sodomy tied to an alleged assault that occurred at a residence in East Cobb sometime between June 1 and August 1, 2025.
According to FOX 5 Atlanta, the report is based on an arrest warrant and a statement from the Cobb County Sheriff's Office, which said authorities did not release the victim's age. Investigators reported that the girl stated Marshman ignored her repeated verbal requests to stop during the encounter, and that he committed forced sexual acts against her.
Warrant Details Point to East Cobb Address, Forensic Interview
Arrest warrant details reported by East Cobb News specify that the alleged assault took place at a residence off Post Oak Tritt Road in East Cobb, while Marshman himself resided at an address on nearby Field Creek Drive off Hembree Road, both prominent residential thoroughfares in the area. The outlet's review of the warrant also states that the minor victim disclosed the allegations during a forensic interview at the SafePath Children's Advocacy Center, describing how Marshman physically restrained her, forcibly engaged in sexual intercourse, and forced oral sex during the single encounter.
SafePath, based in Marietta, is an accredited nonprofit that coordinates law enforcement, prosecutors and child protective staff to conduct child-focused forensic interviews and abuse interventions across Cobb County. The center has assisted more than 30,000 children and families since it opened in 1995. Just months before Marshman's arrest, federal funding announced in February directed technology resources to SafePath to strengthen the county's child abuse investigation infrastructure, according to the office of U.S. Senator Jon Ossoff.
Prior Jail Booking, No Bond Under Georgia Law
Public booking records published by The Georgia Gazette show Marshman was previously booked into the Cobb County Jail on June 11, months before the August 27 arrest that led to the current rape and aggravated sodomy charges. It is unclear from available records what that earlier booking involved or whether it connects to this case.
Marshman was denied bond, per the sheriff's office, and that outcome follows directly from Georgia law. Under Georgia Code § 17-6-1, magistrate court judges lack the authority to set bail for capital offenses and serious violent felonies such as rape and aggravated sodomy — meaning only a Superior Court judge can consider bond in this case. Arrest warrants were filed in the Magistrate Court of Cobb County, and Marshman's next court hearing remains unclear, per the report.
Mandatory Prison Terms and Lifetime Registration at Stake
The charges Marshman faces carry some of the harshest mandatory penalties in Georgia's criminal code. Under Georgia Code § 16-6-1, rape is classified as a non-parolable violent felony carrying a mandatory minimum of 25 years in prison followed by lifetime probation, with a maximum of life without parole. Georgia Code § 16-6-2 defines aggravated sodomy as non-consensual oral or anal sex committed by force or against a victim's will, carrying a potential sentence ranging from 25 years to life in prison.
If convicted, Marshman would also be required to register for life on the Georgia Sex Offender Registry under Georgia Code § 42-1-12, a mandate that applies to those convicted of dangerous sexual offenses including rape and aggravated sodomy. Registered offenders must report any changes to their residence or employment directly to their local county sheriff's office.
The case adds to a string of serious child sexual abuse prosecutions moving through Cobb County this year. Earlier this month, the Cobb County DA secured life plus 490 years against a man convicted of severe child sexual abuse in Cobb Superior Court, illustrating the kind of sentencing outcomes prosecutors have pursued in similarly severe cases. Whether the DA's office has yet presented Marshman's case to a grand jury, and when he might appear before a Superior Court judge for a bond hearing, remain open questions.
