Investigators have moved their search back to the Hartford garbage dump as they look for the remains of missing Connecticut mom, Jennifer Dulos. Jennifer was last seen on May 24 as she dropped her five children off at school.

Jennifer’s estranged husband, Fortis Dulos, has been charged in the case along with his girlfriend Michelle Troconis. Both have been charged with evidence tampering and hindering prosecution. Troconis is cooperating with investigators and has provided them information in their search for Jennifer.

Investigators returned to the trash site on Monday after video surveillance footage allegedly showed Fortis and Tronconis dumping trash into various dumpsters located throughout Hartford the night that Jennifer disappeared. The police have found some bags that contained items that were soaked with Jennifer’s blood, the Stamford Advocate reported.

K-9s were also enlisted in the search to find Jennifer’s body within the garbage facility. The New Canaan police told the Advocate that they are looking for biological fluids related to Jennifer’s case. The police department has also set up a website for the investigation, where they have already received 300 tips and 75 responses to their request for security footage, the news outlet said.

“We urge everyone with information regarding Jennifer’s disappearance to contact us,” New Canaan Police Chief Leon Krolikowski said in a statement to the Advocate. “We will not rest until we find Jennifer.”

Fortis and Troconis are set to appear in court on Tuesday in Stamford, Connecticut. Fortis has hired Norm Pattis, the same lawyer that represented Infowars host Alex Jones and was criticized for posting racial comments on Facebook. Fortis is still being held in the Bridgeport Correction Center on $500,000 bond. Troconis has posted bail.
