CLEVELAND, Oh. -- As investigators work to identify the human remains found buried in a west side yard Tuesday, a woman who lived at the home remains in police custody.

Larissa Rodriguez was taken into custody after a man in Pakistan called Cleveland police with a tip Monday, claiming Rodriguez had buried her 5-year-old son in her W. 80th Street backyard. The caller is believed to be the boy's step-uncle.

When the Cuyahoga County Division of Children's Services arrived at the home, they found it in deplorable conditions. The home was infested with rats and cockroaches, and one of Rodriguez's nine children was seen eating a sandwich that had cockroaches in it.

Authorities later found human remains in the backyard Tuesday. Though the Cuyahoga County Medical Examiner has yet to identify the remains, police say they are consistent with those of a child. An autopsy is scheduled for Wednesday.

Rodriguez initially told police her 5-year-old son Jordan was visiting his father in Houston, Texas, but claimed she had no contact information for him.

Rodriguez's relatives say they last saw Jordan alive July 17. Two weeks later, Rodriguez told them she found Jordan "half-dead" in a closet and that she was sending him away to visit an aunt in Texas. Relatives say Rodriguez said Jordan was still in Texas in August. In October, they say children's services told them all children had been removed from the home.

Relatives also say they've known about the conditions inside Rodriguez's home and reported her to children's protective services several times. They claim CPS visited the home in September. They also said Rodriguez is currently six months pregnant with a baby girl and has had three children taken from her custody.

According to court documents, two other children were removed from the home and placed into the custody of children's services.

Rodriguez has not been charged, but remains in police custody as of Wednesday morning.

A vigil for Jordan is planned for Thursday outside the home.
