A 47-year-old mother of three and former Baltimore Ravens cheerleader is facing charges for an alleged sexual relationship with a 15-year-old boy. 

Molly Shattuck, formerly known as the oldest cheerleader in the NFL, pleaded not guilty to charges of third-degree rape and unlawful sexual contact.

Shattuck allegedly had her first contact with the victim through Instagram after seeing a picture posted by the teen.

Her son is said to have made contact with the teen thereafter, telling him "my mom is obsessed with you" and encouraging him to contact his mother.

FoxNews.com reported: 

On Sept. 26, a 15-year-old boy told police that Shattuck began an inappropriate relationship with him near Baltimore and that it culminated with sexual activity at a vacation rental home in Bethany Beach over Labor Day weekend, said Delaware State Police Sgt. Paul Shavack. Police executed a search warrant on Shattuck's Maryland home Oct. 1 and seized items. Shavack declined to specify what they were.

The indictment alleges Shattuck provided alcohol to three underage boys on Aug. 30 and Aug. 31 and had sexual contact with one of the boys near Aug. 31.

Heather Nauert discussed the case this morning with former prosecutor Fred Tecce and defense attorney Esther Panitch.

Both agreed that it appears Shattuck has some "serious issues" or a possible mental illness. 

Panitch noted that Shattuck's son is just as much of a victim as the other teen. 

Tecce expects a guilty plea at some point, citing overwhelming evidence against Shattuck.
