LANDSDOWNE, Md. -- A child found wandering near her Maryland home with blood on her clothes reportedly said her mother - later found dead - was "bleedy," according to CBS Baltimore.

Police say they're investigating the death of the mother, Brittany Jackson, who was found in an upper floor bathroom of the Landsdowne home where she lived with the girl.

Baltimore County Police announced early Monday that a girl described as about 3 years old was found wandering unattended around 10:30 p.m. Sunday on Hollins Ferry Road in Lansdowne, south of Baltimore.

Hours later, police found her mother dead at the home, about a block away. Police are conducting a death investigation and say there were no obvious signs of foul play.

A Good Samaritan who came to the child's aid, Frank Myers, told CBS Baltimore he was working security at a nearby bar when he spotted her wandering alone.

"We said, 'Excuse me, where's your mother and father?' and she said, 'Well, my mother is bleedy' and she had blood on her," Myers told the station.

The girl had blood on her clothing but was not injured, Cpl. John Wachter, a Baltimore County Police spokesman, told 48 Hours' Crimesider Monday. There's no indication whose blood it was. The deceased woman also had blood on her, Wachter said.

"We became real concerned, overwhelming concern. We wanted to know if her mother was hurt or what happened," Myers told the station. He said he immediately called police and canvassed the area with the girl, but couldn't immediately find her home.

"She was saying she wanted to go see the fishies and her mother was bleedy," Myers said.

An autopsy is set to determine the woman's cause and manner of death.

The girl is in the custody of Baltimore County Social Services.
