Knoxville, TN (WOKI) Ijams Nature Center officials issue a warning Friday about Mead’s Quarry Lake.

Officials say you should not swim in the Quarry right now and neither should your pets.

The lake is suffering a temporary algae bloom which Ijams says has the potential to be toxic to both people and pets.

The bloom was discovered through water quality testing by UT students and faculty during a class.

Officials say until the health advisory is lifted, neither you nor your pets should swim, wade, or come into contact with the water until further notice.

According to officials, symptoms to watch out for include upset stomach, vomiting and diarrhea. Heavy exposure could also result in liver or kidney damage and can harm your pets as well.

The center said it’s working closely with the Tennessee Department of Health and the Tennessee Department of Environment and Conservation to monitor the levels.

If you think you, your family or your pets are experiencing symptoms after swimming in the lake, contact the Tennessee Department of Health. You can e-mail them at [email protected] or call 615-741-7247.

Sumner County, TN (WOKI / WVLT) It’s been nearly a month since an autistic teen disappeared from his Sumner County home, and now the search area is expanding to include West Tennessee.

Middlesboro, KY (WOKI) The Middlesboro Kentucky Police Department says there is a “significant development” in the death of 17-month-old Elena Hembree.

The MPD says an extensive investigation and a DNA result showing a lack of male DNA confirm their findings that the girl’s mother, Erica Lawson, is responsible for the little girl’s death.

She is charged with manslaughter, criminal abuse and other charges.

Additionally, the cause of death has been determined to be non-accidental blunt force trauma.

On July 28 of last year, Hembree showed up at the local hospital with severe injuries. She was flown to Knoxville, but due to the extent of those injuries did not survive.

Nashville, TN (WOKI / WVLT / WSMV) The search for Riley Strain Wednesday at the Cheatham Dam yields no clues in the disappearance of the 22-year-old University of Missouri student.

Officials with the Cheatham County Sheriff’s Office say crews were burping — closing and opening — the dam as part of the search efforts but found nothing connected to Riley. They say no other search efforts are planned in the area at this time.

The Cumberland River runs through the dam which is about 42 miles downstream from Nashville and is operated by the U.S. Army Corp of Engineers.

Strain has been missing since March 8, disappearing after getting kicked out of a Nashville bar while on a fraternity trip.

While a new search effort was underway at the dam Wednesday, search crews continued to search for the 22-year-old in the Cumberland River area in Nashville.
