{{#rendered}} {{/rendered}}A man has been arrested in the gruesome murder of a 5-year-old nine years ago in Massachusetts.
The body of Jeremiah Oliver was found stuffed inside a suitcase on the side of Interstate 190 in April 2014.
Prior to the discovery of his body, Oliver was reported missing in December 2013. However, the missing person status was months late – Oliver hadn't been seen since April of that year.
