DEKALB, Ill. (WTVO) — A 15-year-old girl has been found dead in a DeKalb dumpster after having been reported missing, and police have identified the suspect as a registered sex offender.

According to the DeKalb Police Department, Timothy Doll, 29, has been charged with the murder.

Gracie Sasso-Cleveland was identified as the victim by family friends on GoFundMe.

Police said that Sasso had not been seen by family members since Thursday evening. Phone records indicated that she had been at an address in the 500 block of College Avenue.

Her body was found in that area on Sunday afternoon.

According to Bethany McCall, who started the GoFundMe, Sasso had “just found out the man she thought she was dating was a 29-year-old sex offender with a lengthy rap sheet.”

Police said on May 4th, Doll and Sasso argued after which point he suffocated her with a pillow. He then put her body in a dumpster, police said.

The coroner determined asphyxiation was the cause of her death.

After the crime, Doll allegedly removed all of Sasso’s belongings from his apartment and threw her phone away at another location.

Doll was arrested after a search of a nearby residence. He reportedly knew the victim, police said. Police also said Doll was in custody, but is undergoing a medical procedure before being admitted to the jail.

He has been charged with First Degree Murder, Aggravated Criminal Sexual Abuse, Concealment of a Homicide, Aggravated Domestic Battery, Obstruction of Justice, Unlawful Restraint, and Unlawful Communication by a Child Sex Offender.

Doll has prior convictions for Aggravated Criminal Sexual Assault of a Victim between 13-16. According to Shaw Local, court records showed he was arrested in 2020 after police discovered a video on his phone showing him having sex with an underage teen.

Sasso was a student at DeKalb High School, the Daily Chronicle reported, according to an email, sent by Superintendent Minerva Garcia-Sanchez, to parents on Sunday night.
