A trio of former Pennsylvania high school students were sentenced to probation after they admitted to putting human feces on a cake they gave to a classmate.

Former Avon Grove High School students Mayra Flores, 19, Ana Mireles, 18, and Sandra Ortiz, 18, all of Avondale, were each sentenced to 22 months of probation on conspiracy and reckless endangerment charges after they pleaded guilty Monday and admitted to putting feces on the birthday cake for another student in March, The (West Chester) Daily Local News reported Thursday.

Common Pleas Judge William Mahon stipulated the 200 community service hours required under the probation must be served performing tasks such as cleaning toilets, urinals and bed pans at local senior centers.

Flores and Mireles were also ordered to spend the first two months of their probation sentences on electronic home confinement.
