Victoria Del Carmen was charged with four counts of possession of depictions of minor children engaged in sexually explicit conduct.

The Pierce County Sheriff's Department began investigating when the National Center for Missing and Exploited Children notified officers that child pornography had been shared to an Internet Protocol address in an unincorporated area of the country.

During the investigation, detectives learned that the woman had advertised her babysitting services on Care.com and found text messages indicating she had recently been babysitting several children, according to a Sheriff's Department press release.

Police were able to find the address and executed a search warrant on a residence. While searching the suspect's bedroom, detectives found doll parts and a lifelike baby doll, in addition to diapers, pacifiers and baby clothes. Police also seized electronic devices and found communication about sexual acts with infants and toddlers.

The evidence in the bedroom indicated to detectives that there may be additional victims, according to the press release.
