Cedar Lake Woman Sentenced to 15 Months in Prison For Bank Fraud

HAMMOND - Katie M. Tristan, 41 years old, of Cedar Lake, was sentenced by United States District Court Judge Gretchen S. Lund after pleading guilty to bank fraud, announced U.S. Attorney Adam L. Mildred.

Tristan was sentenced to 15 months in prison followed by 2 years of supervised release. Tristan was also ordered to pay $125,157.67 in restitution to the victims of the offense. Of that amount, which was paid in full at sentencing, $123,192.22 will be returned to the Hanover Community School District.

According to documents in the case, between October 2020 and June of 2023, Tristan used her leadership positions in the parent-teacher organizations (PTOs) at two Cedar Lake elementary schools to embezzle over $107,000 in funds that had been donated to support extracurricular programming. For a period of over two years, Tristan used the PTO debit cards for personal expenses including car rentals, travel and entertainment, utility payments, and retail shopping. Once Tristan had exhausted the PTOs' funds, she executed a series of fraudulent check transactions to falsely inflate the balances of the PTO bank accounts and prolong the fraud.

When school administrators and the Cedar Lake Police Department began investigating the missing PTO funds, Tristan obstructed those investigations by forging bank documents and using fake email accounts to impersonate other PTO volunteers. In September 2023, Tristan used a fake email account to impersonate the Cedar Lake Police detective handling the investigation, enabling her to manipulate the detective's communications with a key witness.

"By stealing from her parent-teacher organization (PTO), Katie Tristan stole from the children that she had supposedly volunteered to help," said U.S. Attorney Mildred. "Money meant to support their education and personal growth was diverted to funded her personal wants and expenses to the tune of $107,000. She compounded her crime through blatant fraud and obstruction designed to hide the fact that she was a thief. Thankfully, the law enforcement professionals from the FBI, Cedar Lake Police Department, and our office saw to it that justice was served. While Tristan failed to honor her duties as a PTO volunteer, her example can at least serve to teach other would-be fraudsters a valuable lesson-if you steal from Hoosier students, you will be held accountable."

"Tristan sought out and obtained a position of trust in the Cedar Lake elementary schools and then violated the trust the community placed in her," said Timothy J. O'Malley, Special Agent in Charge of the FBI's Indianapolis Office. "The FBI is proud to have worked this investigation with the Cedar Lake Police Department and the U.S. Attorney's Office to help protect a local Indiana community."

This case was investigated by the Federal Bureau of Investigation and the Cedar Lake Police Department. The case was prosecuted by Assistant United States Attorney Zachary D. Heater.
