A mother and her two sons have been convicted of fraud in what police call a major, complex mortgage scheme worth over $1.2 million.

The investigation started back in the winter of 2008, when detectives responded to a single mortgage fraud complaint. That lone complaint led to police discovering a complex fraud scheme involving five victims of stolen identity — three from Kitchener, and two from Hamilton.

The case involved seven mortgages, one line of credit, and five residential properties in Hamilton and one in Simcoe, police say. The total losses to four banks were over $1.2 million.

On Monday, Judge Robert J. Nightingale found a mother and her two sons guilty on a slew of fraud charges.

Shan Lal was found guilty of two counts of fraud over $5,000 and one count of money laundering.

Her son Allan Mohammed was found guilty of seven counts of fraud over $5,000 and one count of money laundering.

His brother Andre Mohammed was found guilty of uttering forged documents and two counts of fraud over $5,000. He was also acquitted on one other fraud charge.

All three are out of custody and expected back in court at the end of August for sentencing submissions.

Three other people involved in the case pled guilty on fraud charges in 2010 and 2011.
