So Shannon Beck (suspect) must have been pretty far along in her pregnancy to try and pass off a newborn baby as her own. Glad family members were alert to the situation and noticed the makeup covering the birthmark.
I believe so... the sister-in-law that turned her in had also just had a baby.
On Sunday, Beck contacted Torrez to say she had given birth, Corvington said. Beck had been pregnant but apparently miscarried shortly before her own child was to be born.
Torrez visited Beck on Monday and urged her to take the child to a doctor, the FBI agent said. Beck agreed, and Torrez accompanied her to St. Louis on Tuesday, about 45 miles away.
Torrez noticed what appeared to be makeup on the baby's forehead, Corvington said. When she rubbed the forehead, makeup came off what was covering a small birthmark.
In publicizing the abduction, police had described Abby's strawberry-red birthmark. Her suspicions aroused, Torrez confronted Beck, who gave her the baby, Corvington said.
Torrez contacted police, and the baby was handed over to authorities around 5 p.m. Tuesday.
