From that article:

Alexis was working for a computer contractor, Suthamtewakul said.

and

Somsak Srisan, who owns the property at 7940 White Settlement Road, said Alexis has not lived there for six to eight months.

Speculation: Did the contractor who employed Alexis lose a contract with the Navy, perhaps causing Alexis to be laid off?
