Good news comes in from Knoxville, where two daughters of a Hamilton County deputy have undergone treatment for E. coli.

WDEF-TV reports that three out of four of Mark King’s children came down with the bacteria in mid-July.

Doctors released 8 year old Kelsey from the hospital over the weekend and upgraded the condition of her four-year-old sister Lexie from critical to serious. One-year old Harley is already home.

The Health Department still has not determined where the family contracted the E. coli.
