ATLANTA (AP) — The woman accused of posing as a nurse while caring for Bobbi Kristina Brown at a Georgia hospice facility was investigated last year in Maryland for allegedly working as an unlicensed nurse at four facilities there.

Maryland Board of Nursing executive director Mary Kay Goetter told The Associated Press on Friday that Taiwo Sobamowo used another person’s name and license number to obtain the jobs between 2010 and 2013.

Goetter said the Maryland board began investigating in January 2014 after the District of Columbia Board of Nursing issued a warning that Sobamowo had impersonated a nurse to work at a hospice facility in Washington.

Brown, the 22-year-old daughter of singers Bobby Brown and the late Whitney Houston, died July 26 at Peachtree Christian Hospice in Duluth, Georgia.
