Police: Blood, feces-stained letter sent to mother of suspect in murder of NY jogger

HOWARD BEACH, Queens -- A gruesome letter was sent to the mother of the Brooklyn man suspected of killing Karina Vetrano.

Police say Veta Lewis received a letter stained with blood and feces demanding an apology. Her son, Chanel, was arrested and charged in February with the rape and murder of 30-year-old Vetrano.

Vetrano was killed after going for a jog in Howard Beach in August.

The NYPD has opened an investigation into the letter.
