A woman in Hawaii is pleading guilty to sending her husband in New Jersey more than half a million dollars she earned working as a prostitute.

Khemwika Ernst pleaded guilty Monday in federal court in Honolulu to a conspiracy charge and filing false tax returns.

Prosecutors say more than $525,000 can be traced to her working as a prostitute from 2008 to 2014.

Ernst and her husband were indicted in March. According to court records, Michael Ernst shot and killed himself a month later.

Through a Thai-speaking interpreter, Khemwika Ernst said she and her husband used some of the money to buy a house in Newton, New Jersey.

She faces up to five years in prison when she’s sentenced in January.
