Portland police said the heart was left in a box Wednesday on the front porch of a home in the 2300 block of Northwest Flanders Street and the Oregon State Medical Examiner's Office identified the organ as a cow heart, KGW-TV, Portland, reported Thursday.
James Lynch, a resident at the home, said there was a note left in the mailbox that said something similar to "my heart is yours forever."
"I can't even explain it or even know why someone would do it," Lynch said. "Kind of bizarre."
