Table of Contents

Version Summary

This policy guide was updated from the 12/23/14 version to address how and when it is most appropriate for CSWs to utilize law enforcement in responding to families. The policy was also revised to clarify information regarding consent for medical examinations by children over the age of 12 during investigations


Concurrent Investigations with Law Enforcement

Both DCFS and law enforcement have the authority to investigate cases of suspected child abuse or neglect and to take children into temporary custody when required.

Completing concurrent investigations with law enforcement requires that DCFS and law enforcement make efforts to communicate from the earliest opportunity, coordinate investigations, limit repeat interviews by different agencies, and continue to share information throughout the investigation of the case. 

When law enforcement and DCFS are completing concurrent investigations, each agency must adhere to its’ separate mandates.  Law enforcement has authority to determine whether a crime has occurred.  DCFS has authority to determine whether the child requires protective services. 

When law enforcement detains or delivers (not detained) a child to DCFS, per WIC 306 and/or 309, a safety assessment must be conducted by the CSW to determine if the child should be taken into temporary custody. To take a child into temporary custody, a CSW must have one of the following:

  • consent
  • exigent circumstances
  • court order

When law enforcement has taken a child into temporary custody and it is determined by DCFS that the child(ren) can return home permanently or pending a removal order, ARA approval and notification to law enforcement is required.

If the situation warrants it, a CSW should call law enforcement for assistance when investigating a child abuse referral and/or taking a child into temporary custody. 

Please note that Law Enforcement should accompany a CSW under the following circumstances:

  • Personal safety
  • Serving removal orders
  • Serving search warrants

Concurrent Investigation Referrals

A concurrent investigation with law enforcement must be conducted, whenever possible, on any of the following types of referrals:

  • Physical abuse
  • Sexual abuse
  • Severe neglect
  • Domestic violence (in some instances)
  • Any type of referral where law enforcement and DCFS mutually agree to conduct a concurrent investigation.

Cases requiring a concurrent investigation with law enforcement may be designated as either immediate or expedited referrals. A concurrent investigation with law enforcement can be conducted by any of the following staff:

  • Regional CSW responding to a referral (ER or FM/R)
  • Law enforcement co-located CSWs
    • Law enforcement co-located CSWs must adhere to Emergency Response policies & procedures and respond to referrals within the community of the law enforcement agency. 
    • When Emergency Response Command Post (ERCP) transfers a referral or case in which a Concurrent Investigation with law enforcement was conducted, the newly assigned CSW has the responsibility of informing the officer and/or detective of the new assignment.

Responding Without a Referral

In some situations, DCFS has a legal obligation to receive temporary custody of a child who has been delivered by a peace officer, with or without a referral.  If a child (dependent or non-dependent) is transported by law enforcement to a DCFS office and a child abuse referral has not been made, law enforcement must call the Child Protection Hotline to make a child abuse referral.

CSWs are authorized to protect children without a referral and take them into temporary custody as long as there is reasonable cause to believe that the child is:

  • A minor who has been declared a dependent child of the juvenile court under Section 300.
  • A minor as described in subdivision (b) or (g) of WIC Section 300 and the social worker has reasonable cause to believe any of the following:
    • The child has an immediate need for medical care.
    • The child is in immediate danger of physical or sexual abuse.
    • The physical environment poses an immediate threat to the child’s health or safety.

CSWs are allowed to conduct a concurrent investigation with law enforcement without a referral, per WIC 306(a).  MART CSWs and co-located ER CSWs are the primary CSWs that respond without a referral; however law enforcement may directly contact a regional office for ER CSW assistance. As soon as the CSW responds to the location to meet law enforcement, the CSW must inquire if law enforcement called in the referral to the hotline.  If it was done, the CSW must obtain the 19 digit referral number from law enforcement.  If it was not done, the CSW must request that law enforcement call in the referral immediately and the CSW must obtain the 19 digit referral number prior to leaving the location.

CSWs may only assist with the placement of child(ren) whose parents have been arrested if law enforcement has detained a child(ren) under WIC 300, 305(a-d), and/or 309 and a referral has been generated to investigate child abuse or neglect.  A referral needs to be generated for CSWs to complete a criminal history check on relatives or nonrelative extended family members identified as a temporary caretaker by the arrested parent(s).

CSWs, however, can assist law enforcement obtain child welfare history on the potential caregiver identified by the arrested parent(s) via a search on CWS/CMS without a referral.

Communication and Confidentiality

In concurrent investigations, CSWs are required to share information with law enforcement to the extent permitted by law.

When DCFS and law enforcement are both investigating the same child abuse referral, the documents that generated the child abuse referral may be shared without law enforcement having to complete the Declaration in Support of Access to Juvenile Records

Documents that generate a child abuse referral may include the following:

  • Medical reports and documents
  • Therapist reports
  • Police reports

All new incidents of suspected child abuse or severe neglect must be cross-reported to law enforcement.  Additional disclosure of cross-reported information must be discussed among the professionals affiliated with the case.

Many of the documents and proceedings relating to minors are confidential by statute, case law, and/or court order.  Dependency court proceedings and records are confidential; however, criminal court proceedings are not confidential.  When the crime involves a sexual offense, the victim’s identity can remain confidential upon request and not be disclosed on any public records.  In addition, the victim may, at the judge’s discretion, be addressed as Jane or John Doe in court records and in court.

Crime Scene Preservation

During concurrent investigations, CSWs are to avoid disturbing potential forensic evidence and communicate the existence and location of potential forensic evidence to law enforcement. Potential forensic evidence may include but is not limited to:

  • Clothing
  • Bedding
  • Photographs
  • Computer hardware and software
  • Videotapes
  • Sex toys
  • Cell phones
  • Condoms
  • Blood or bodily fluids
  • Weapons
  • Drugs and/or drug paraphernalia
  • Other items which corroborate the child’s allegation

Medical Examinations

During the course of a concurrent investigation with law enforcement where there is evidence/suspicion of sexual or physical abuse, a medical examination of the child should be performed by health care providers with expertise in the area of detecting and diagnosing abuse and neglect. Medical examinations are an important component of investigations in that they can yield forensic evidence and/or expert testimony that is admissible in both dependency and criminal court.

Medical exams (either forensic or to detect and treat child abuse injuries and neglect) are prohibited unless one or more of the following conditions exist:

  • Parental consent
  • A court order
  • Exigent circumstances which demonstrate either:
    • A medical emergency (urgent problem requiring immediate medical attention)
    • That the examination is necessary to preserve evidence (e.g. sexual assault occurring within the previous 72 hours)

Children over 12 must consent to the exam themselves. The exam should not be performed by force on children of any age.

Minors that are 12 years of age or older and who are alleged to have been raped, may consent to medical care related to the diagnosis or treatment of the condition and the collection of medical evidence with regard to the alleged rape. (Family Code § 6927)

A minor of any age who is the alleged victim of sexual assault may consent to medical care related to the diagnosis and treatment of the condition well as the collection of medical evidence with regard to the alleged sexual assault. (Family Code § 6928(b)). When obtaining consent from the youth, the CSW should also advise youth of their right not to consent, in order to ensure that the youth fully understands their rights and not feel forced to consent.

Requests for investigative/evidentiary medical examinations where exigent circumstances do not exist should be made at a court hearing, in a warrant application,  through parental consent or consent of the youth in instances of rape or sexual assault as noted above.
