Here are two links. The top is for a tax advocate, which is a person trained to help you with tax problems. Their service is free and they are sponsored by the IRS.
The second link is to find a tax volunteer service, again sponsored by the IRS.
They might help since they would be better prepared to fill out the forms you need and help you file. The old employee may have made off with your tax withholdings, and if so, the tax advocate might help with that investigation and tax recovery. They can also help you piece things together using your paystubs.
