Oregon authorities have charged music teacher Derek Douglas Reeder with raping, sexually abusing, assaulting, and kidnapping a minor he met through an Oregon City nonprofit.
Reeder, 44, worked as a music instructor at Hannah Grace Family. The nonprofit provides programs for children and families facing instability. Prosecutors say Reeder met the alleged victim in 2023 when she was 13 and quickly began grooming her for sexual contact.
Hannah Grace Family fired Reeder in 2024. However, investigators allege that Reeder continued communicating with the child through Instagram and text messages. They accuse him of sexually abusing her multiple times between 2024 and January 2026.
Reeder later operated Slinky Strings, a private guitar and acoustic-music business that served students of all ages in downtown Oregon City. Detectives believe additional victims may exist.

Charges Against Derek Douglas Reeder
A Clackamas County grand jury indicted Reeder in August 2026. He faces the following charges:
- Two counts of first-degree rape and second-degree sexual abuse
- One count of second-degree kidnapping, second-degree assault, fourth-degree assault, giving marijuana to a person under 18
Clackamas County Sheriff’s Office investigators arrested Reeder on August 20 with assistance from the U.S. Marshals Service. Deputies took him into custody near his downtown Oregon City music business.
A judge ordered Reeder to avoid contact with the alleged victim. Prosecutors also requested a $500,000 security amount during his arraignment.
The charges remain allegations. Reeder remains presumed innocent unless a court finds him guilty.
Derek Douglas Reeder Allegedly Met the Child Through Hannah Grace Family
Reeder reportedly met the child while teaching music at Hannah Grace Family in the summer of 2023.
The Oregon City nonprofit describes its mission as providing hope and healing to children and families who face instability. Its programs include year-long keyboard and guitar lessons for children. The organization provides instruments to participating students and allows them to keep those instruments after completing the program.
That mission makes the allegations particularly troubling. Organizations that serve children who have experienced trauma, foster care, family instability, or economic hardship must enforce strong safeguards.
Children facing instability may crave attention, consistency, mentorship, and approval. An alleged offender can exploit those needs to gain trust, build secrecy, and blur boundaries.
Prosecutors Accuse Reeder of Grooming the Child
During Reeder’s arraignment, prosecutors alleged that he met the girl when she was 13 and quickly groomed her for sexual contact.
Grooming often develops through conduct that appears helpful or supportive. An adult may offer private lessons, special attention, gifts, transportation, emotional support, or direct communication outside the program.
The adult may then test boundaries and encourage secrecy. Digital communication can extend that access beyond classrooms and scheduled lessons.
Investigators allege that Reeder communicated with the child through text messages and Instagram. They say the alleged abuse occurred on multiple occasions after Hannah Grace Family ended his employment.
Organizations that serve children must strictly control electronic communication between staff members and minors. They should require staff members to use monitored accounts, include parents in communications, and prohibit private social-media contact.
Why Did Hannah Grace Family Fire Reeder?
Public reports state that Hannah Grace Family fired Reeder in 2024. However, the organization has not publicly explained why it ended his employment.
That question matters.
Investigators should determine:
- Why did the nonprofit fire Reeder?
- Did anyone report boundary violations or inappropriate communication?
- Document concerns about his conduct?
- Notify the child’s parents or guardians?
- Report any suspected abuse to authorities?
- Warn other organizations or music programs?
- Reeder maintain access to former students after his termination?
- The nonprofit monitor electronic communication between instructors and children?
- Staff members receive grooming-prevention training
- Has Reeder teach students alone?
The available reporting does not establish that Hannah Grace Family knew about the alleged sexual abuse before investigators contacted the organization. FOX 12 reported that it requested a comment from the nonprofit.
Nevertheless, the organization must preserve Reeder’s personnel file, complaints, emails, text messages, training records, student lists, and termination documents.
Reeder Continued Teaching Through Slinky Strings
After leaving Hannah Grace Family, Reeder continued teaching guitar and acoustic music through Slinky Strings. The private business operated from the Harding Building on Main Street in Oregon City.
Authorities say Reeder taught students of all ages through the business. That access has prompted investigators to search for additional victims.
Private music lessons can create opportunities for isolation. Instructors often work one-on-one with students behind closed doors. They may also communicate directly with students, schedule lessons outside traditional hours, and build close mentoring relationships.
Music schools and private instructors should adopt safeguards that include:
- Windows or open doors in lesson rooms
- Parent access during lessons
- Security cameras in common areas
- Prohibitions against private social-media contact
- Written communication policies
- Background checks
- Clear physical-boundary rules
- Multiple reporting options
- Immediate investigation of complaints
Parents should also have the ability to observe lessons and review all electronic communication.
Detectives Seek Additional Victims
The Clackamas County Sheriff’s Office believes Reeder may have abused other children.
That concern requires a broad investigation into every setting where Reeder taught, volunteered, mentored, or interacted with minors. Investigators should contact former students and families through trauma-informed outreach.
Anyone with information may contact the Clackamas County Sheriff’s Office Tip Line at (503) 723-4949 or submit information through the department’s online tip form. Refer to Case No. 26-001816.
Can a Nonprofit Face Civil Liability for Sexual Abuse?
Potentially. A nonprofit may face civil liability when its negligent actions allow an employee to abuse a child.
Relevant claims may involve negligent hiring, supervision, retention. Failure to investigate complaints, report suspected abuse, warn families after terminating an employee, control employee communications with minor or inadequate child-protection policies.
A civil investigation should examine what the organization knew, when it learned of any concerns, why it fired the employee, and whether it took steps to protect current and former students.
Civil litigation can also uncover internal records that reveal whether staff members missed warning signs or failed to follow required safeguards.

Speaking With a Sexual Abuse Lawyer About Your Rights
Parents trust music teachers, nonprofits, and youth programs to protect children. These organizations must carefully screen instructors, monitor private lessons, control digital communication, and act immediately when warning signs appear.
When a teacher allegedly uses a position of trust to groom and sexually abuse a child, accountability cannot stop with the alleged perpetrator. Investigators must also examine every organization that provided access, authority, or credibility.
