Police said a central Pennsylvania couple did not call the bank when a $1,772.50 deposit showed up in their account as $177,250.
Authorities believe 50-year-old Randy Pratt and 36-year-old Melissa Marie Pratt took out the money, quit their jobs and moved to Florida.
The two were arraigned Tuesday and jailed in lieu of $100,000 bail. District Judge Donna Coombe said a public defender and a conflicts lawyer are being assigned.
Police reported that Melissa Pratt deposited the check at FNB Bank last summer.
When the big balance showed up, investigators say, the two wrote checks to another account, bought a new vehicle and were buying a house in the Orlando area when the mistake was traced.
Police said Melissa Pratt told them her husband often got large checks and she wasn't aware of any banking error.
