The family of a baby cut from his mother's womb recently received medical bills totaling $300,000. And what's worse is that the baby was referred to as "Figueroa, boy." Figueroa is the last name of the woman who allegedly murdered his mother.

Clarisa Figueroa was brought to the hospital, claiming she had given birth to him and he wasn't breathing. She then proceeded to care for the baby as if he were her own.

“It’s hard for me to understand the lack of humanity,” the family's lawyer, Frank Avila, tells PEOPLE of the hospital's error.

Avila says that even after the baby died, the family received bills from Advocate Christ Medical Center. All the bills said "Figueroa, boy," even though Figueroa had been arrested. He also says that the hospital promised to write off the bills given the situation. However, they never put it in writing, which is why the family is still receiving bills.

According to the authorities, the baby's mother, Marlen Ochoa-Lopez, who was nine month pregnant was killed in April. Figueroa had gotten Ochoa-Lopez to come to her home under the pretense of giving her free baby stuff. Then, the prosecution alleges that Figueroa choked Ochoa-Lopez with a coaxial cable. She then cut the baby from his mother's womb.

When Figueroa and her alleged accomplice, daughter Desiree Figueroa recently had a bail hearing, new charges were added. Prosecutors presented new first degree murder charges for both women, the Chicago Sun Times reports. The prosecutors are saying the baby, Yovanny Jadiel Lopez, died in June. His death was due to injuries from the lack of oxygen when he was cut from his mother's body. Both women were denied bail.

The Lopez family, through Avila, shared a bill with PEOPLE. It says that the “balance is past due. Please pay the entire amount … to avoid being referred to an external collection agency.”

Naturally, the family is still in deep mourning. And this incredibly careless "inadvertent billing," as the hospital claims, is only making things worse for them.

“My client is overwhelmed by all this,”Avila says. In addition to dealing with the death of his son and wife, Lopez is now a single father to the couple's toddler.

"We have had discussions with the family regarding inadvertent billing and we regret this error," the hospital says in a statement PEOPLE were able to obtain. The statement adds that due to "privacy," they couldn't provide any additional details.
