UPDATE: Richard Henderson found guilty in connection with Diamond Bradley's murder

Richard Henderson has been sentenced to 53 years in prison following the murder of 16-year-old Diamond Bradley.

Henderson was found guilty of murder and officials say the other charges against Hnederson have been dropped.

Henderson was arrested earlier this year after officials found Diamond's body in Putnam County.

A man has been arrested in the death of an Illinois teenager last month. The body of 16-year-old Diamond Bradley was found in Putnam County two weeks ago. Authorities say she died as a result of multiple stab wounds.

Bradley was a junior at Hall High School in Spring Valley, IL. School administrators say she was last enrolled in October 2017.

Over 200 attended her funeral last Saturday, including many students and faculty.

Hall High School Interim Superintendent Jay McCracken says it's been a difficult time for the district.

"As tragic as this is and as saddened as we are, it's still been very heartwarming to see people pull together and help people who are in need," he says.

On Tuesday, February 6, the Putnam County Sheriff announced 26-year-old Richard Henderson of Standard, Ill. was arrested and charged with concealment of a homicidal death. Officials expect more charges at a later date.

Authorities say they believe the two met through the internet and agreed to meet the morning that Bradley was reported missing. Henderson picked Bradley up near her residence and drove directly into Putnam County. A physical altercation occurred, resulting in Henderson killing Diamond.

Henderson is currently being held in the Lasalle County Jail.
