BALTIMORE, OCT. 27 -- Authorities are looking for a 44-year-old woman who fled with a baby after being questioned by police about the June kidnaping of a 2-day-old infant from Johns Hopkins Hospital, police said.

Baltimore police issued kidnaping and abduction warrants today for the arrest of Dorothy Jean Brown of the Baltimore suburb of Riesterstown, who fled Sunday, said police spokesman Dennis Hill.

"We are now thoroughly convinced that she is the one who took the baby from Hopkins hospital," Hill said.

An anonymous caller notified police last week about Brown, who claimed to have recently given birth to the infant she named Tony Gilmore Jr. She became a suspect after police found discrepancies the account of her pregnancy and birth, said police spokesman Dennis Hill.

On June 18, Kendol Kearnes disappeared from his mother's hospital room at Hopkins. Police mounted a massive search and a reward was offered for information about the abduction, the second from a Maryland hospital this year.

Police, who said there was no connection between the Kearnes kidnaping and the abduction of a baby from Prince George's Hospital Center on June 11, reported few leads in the case until the anonymous call last week.

The woman and her family members were questioned after the call last week, Hill said. Investigators found that she never had been admitted to the hospital where she claimed she gave birth to the child. Police had asked the woman Friday to submit herself and the child to a blood test Monday, Hill said.

The woman's boyfriend, Tony Gilmore, called police Monday to say Brown disappeared Sunday morning after leaving home by bus with the infant. She had said she was going to drop off the infant at her mother's Baltimore home before going to work as a security guard at the Baltimore Museum of Art. She never arrived at either place, Hill said.

Police said Brown had medical problems that prevented her from having a child of her own.
