(NEWSER) – The details surrounding how a pregnant mother managed to plow her minivan into the ocean with three kids on board just got more bizarre: Police say they pulled Ebony Wilkerson over hours before the incident after her sister reported that she was "not all here," NBC News reports. "She's talking about Jesus, that there's demons in the house," said the sister. "She's got the kids in the car with her." Wilkerson told police, however, she was afraid her ex-husband would find and hurt her and her children, so she was going to her "safe place." And though she wouldn't tell police where that was, they found no reason to detain her, WESH reports.
