TAMPA, Fla. – Investigators with the Tampa Police Department officially closed its investigation into steaks laced with LSD, according to news reports.

In March, a family of four was rushed to a local hospital after eating steaks laced with LSD. Jessica Rosado, one of the victims, was nine months pregnant at the time. Doctors delivered the baby via C-section. Rosado's two daughters, ages 6 and 7, also were rushed to the hospital along with Rosado's partner, Ronnie Morales.

The family bought the steaks from a Tampa, Fla. Walmart. But an investigation launched by police and Walmart found no obvious signs of tampering.
