A military veteran couple paid more than $400,000 toward a new home, then had to cover another $116,085 in subcontractor and supplier bills, according to a Missouri investigator. The company allegedly abandoned the unfinished project after receiving money intended to pay for that work and those materials.
Donald B. Erwin, 51, was booked into the Barry County Jail on November 10, 2026. Investigators identified him as a managerial agent of Endless Concepts Contracting and a co-owner of Boss Hog Barndominiums, the businesses involved in the complaints.
The Missouri Attorney General’s Office received at least 45 consumer complaints concerning the companies, which an investigator said collected approximately $5 million from complainants. A probable cause statement details five customer cases with $910,672.49 in alleged losses, a separate figure from the broader total of customer payments.
Amanda Jane Ross and William “David” Ross, identified in the filing as Endless Concepts’ owners, remained wanted as of November 11, according to Newstalk KZRG’s report. The sheriff’s office is seeking information about their whereabouts.
The Couple Paid Again for Work and Materials Already Funded
The three-page probable cause statement says Roger and Karen Watkins signed a $532,076 barndominium construction agreement with Erwin on October 23, 2024. Both are military veterans, and the filing identifies Karen as a disabled veteran.
Between October 2024 and November 2025, the Watkinses paid Endless Concepts $400,448.52. Investigator Jim Garrett wrote that the company abandoned the incomplete project and failed to pay subcontractors and vendors $116,085.27, which the couple had to cover despite already providing the money to the contractor.
The statement also says they spent approximately $24,000 correcting defective work attributed to inadequate plans. Garrett separately estimated the Watkinses’ alleged damages at $294,246.52.
Other Customers Allegedly Received No Work or Refund
Christopher Mortimer paid $4,500 for architectural plans before signing a $449,291.74 homebuilding agreement with Erwin in April 2025. Garrett wrote that Mortimer then paid $327,419.04 between April 2025 and February 2026 but received no labor, materials or refund of that amount.
Two other customers, David Diaz and Harry Diaz, transferred $128,848.18 and $63,857.68, respectively, after signing separate construction contracts. According to the statement, neither received the promised work, and the company failed to honor signed termination agreements providing for refunds.
Doug and Jill Carlon signed a $943,288.18 construction agreement in January 2025 and transferred $96,301.07 that September. Investigators allege the company supplied no labor or materials and did not return their money.
Investigators Trace Payments and Question Professional Stamps
Garrett’s statement describes Erwin as someone who signed contracts and made representations on Endless Concepts’ behalf. It says records showed he held a 25% ownership interest in Boss Hog and used titles including vice president of national construction.
Investigators traced customer payments into Endless Concepts accounts at Barry County bank branches controlled by the Rosses. Money was then transferred into Boss Hog accounts at JPMorgan Chase, where Amanda Ross and Erwin were authorized signatories, according to the filing.
The complaints also concerned the building plans customers purchased before construction. Garrett alleged that some plans could not safely be used to build homes and that certain documents bore forged architect or engineering stamps.
Erwin Faces 10 Felony Counts and Seeks a Lower Bond
The November 9 felony complaint charges Erwin with three counts of stealing, five counts of deceptive business practices and two counts of financial exploitation of a disabled person. Counts IX and X concern the Watkinses’ payments and the promised construction.
In a five-page excerpt of the November 11 bond motion, Erwin’s lawyers asked the court to remove or substantially reduce his $1.3 million cash-only bond. They argued that he had no criminal record or history of failing to appear and had not attempted to flee despite knowing of the investigation for more than six months. The motion requested a bond of $50,000 or less, in cash or through a surety, or a property bond.
The case docket reviewed November 12 did not yet show a ruling on that request. KZRG reported that Amanda Ross faces 15 felony counts and David Ross faces four; all three defendants are presumed innocent unless proven guilty.

Check Subcontractor Payments and Verify Building Plans
The Missouri Attorney General’s Office recommends a written contract specifying the work, price and completion date, and inspecting work before payment. Missouri’s statutory notice to homeowners warns that unpaid subcontractors or suppliers can lead to a mechanic’s lien and advises requesting lien waivers to avoid paying for the same work or materials twice.
When plans carry an architect’s or engineer’s seal, check the professional’s credentials with the relevant state licensing board; Missouri provides a licensee search. Contact the professional independently to confirm that they approved the specific plans, since an active license alone does not authenticate a document bearing their name.
Keep contracts, payment records, correspondence, plans and photographs of construction progress. Suspected contractor fraud can be reported through the Missouri Attorney General’s consumer complaint form or at 800-392-8222, with copies of supporting documents.
