According to police, a customer noticed the woman—later identified as 38-year-old Mary Grace Trinidad—bleeding as she left the restroom of the Subway location in West Covina on Monday morning. The customer went inside and found a newborn crying with the umbilical cord attached, says police Cpl. Rudy Lopez. "The baby was in the toilet," Lopez says. He didn't say whether Trinidad had given birth in the toilet, but the placenta was found in the restroom trash, per KTLA. Trinidad left a trail of blood and was arrested about 20 minutes later in an alley behind a Pep Boys. As a precautionary measure, she was taken to hospital—the same hospital where the little boy was taken in critical condition, though they were kept apart, CBS Los Angeles reports. Already sought on a drug-related warrant, Trinidad was booked on suspicion of child endangerment and attempted murder. Employees at a nearby restaurant say she was familiar to them and asked for food daily. "I’ve done this for 36 years," says Lopez. "I thought I had seen everything. I have no words to describe how I’m feeling about this."
