A Baltimore County mother who was raped in May made a rare personal and emotional plea yesterday for the public's help in finding the man who "continued to beat me as I begged for my life."

"Then, he strangled me until I lost consciousness," said the Pikesville woman, who was seven months' pregnant with her sixth child at the time. The baby survived.

"This attack caused me to sustain permanent injuries," the victim said. "My pregnancy was complicated following the attack and my unborn child was also injured. My baby was then born prematurely."

The short, dark-haired woman in her early 40s made the appeal at a news conference at Baltimore County police headquarters in Towson.

The victim, who was not identified, spoke a few minutes before police released an audiotape of one of two 911 calls made the night of May 15, when the rape occurred. Police believe the second 911 call may have been made by the woman's attacker.

Police wouldn't give details as to why they suspect that, but the caller notified police of a woman being in trouble and needing help behind a Cockeysville swim club. The victim believes the caller is her attacker, said police spokesman Bill Toohey.

The woman's appeal is unusual, said Toohey, and was made because "she wants to do her part to get the attacker caught."

The woman left her apartment that spring evening and walked to an automated teller machine in the Greenspring Shopping Center in the 2800 block of Smith Ave., when she was approached by a man in the parking lot about 10:30 p.m., according to police reports.

"Suddenly, I was viciously attacked by a person who struck me in the head and face. I begged him not to hurt me, telling him that I was pregnant and the mother of five children," the Pikesville woman said.

Her attacker then strangled her, causing her to lose consciousness, she said.

Finally, she began to regain consciousness. But the attacker restrained her and forced her into a car, which he drove to an industrial park in Cockeysville.

"There, on a parking lot, I was violently sexually assaulted," she said, wiping tears. "I was pleading with him not to kill me. He left me on the ground, alone, injured and terrified."

After the attacker fled, she walked to a nearby business and a man there called 911 for help.

Shortly after, Toohey said, police received a second 911 call from a man who reported seeing a man dumping a girl off behind the Beaver Dam Swim Club.

The caller, who wouldn't give his name or telephone number, said the man had driven away and left the woman behind the swim club on Lakefront Drive, where there are several light industrial and office parks and parking lots. The caller described the man as a white male in his 30s, driving an older-model white Honda Accord with a hatchback -- facts confirmed by the victim.

After the attack, the victim spent several days being treated for head injuries at Greater Baltimore Medical Center in Towson. Doctors there also prevented the woman from having a miscarriage.

The victim said she is determined to overcome the trauma.

"I am equally determined to see that the person who did these horrible things to me is apprehended and prosecuted to the fullest extent of the law," she said. "I do not want anyone else to suffer as I have."

Police are asking that anyone with information call 410-307-2020 or Metro Crime Stoppers at 410-276-8888. A $2,000 reward is being offered for information leading to an arrest and indictment.
