She faces a maximum sentence of 90 years in prison.
Crump previously worked at the Simpson and McGee Mortuary in Lynwood, which no longer exists.
Prosecutors said Crump filed fraudulent claims against $1.2 million in life insurance policies for a person who had not died. She and her accomplices obtained bogus death certificates, bought a burial plot, buried an empty casket, and staged a phony funeral.
After two insurance companies became suspicious, investigators said Crump and her accomplices had the casket cremated. They even filed false documents with Los Angeles County, claiming the remains were cremated and scattered at sea.
Crump and her accomplices are also accused of defrauding several companies that provide cash advances in order to help to cover funeral costs. The advance is in exchange for a portion of the deceased person's life insurance policies.
Crump is scheduled to be sentenced in November.
