Cops searching for a teen who vanished 10 years ago are excavating a nearby house after a radar detected “anomalies” underground, authorities said this week.

The major dig at a house in South Elgin, Illinois, started early Thursday — exactly 10 years and a day after Kianna Galvin, then 17, was last seen, having told her sister she was heading to a park on Mother’s Day.

“The excavation is being conducted after investigators scanned the property with ground-penetrating radar,” the Kane County State’s Attorney’s Office announced of the property just a few blocks from where Galvin lived.

“The GPR scan revealed anomalies beneath the surface that detectives determined warranted further investigation,” the statement said, without elaborating on exactly what was seen.

Tents were erected at the back of the home and cops were seen walking out with evidence, WLS reported. 

The dig was proof that authorities have never given up trying to get answers for Galvin’s family, the prosecutor’s office said.

“Ten years have passed since Kianna disappeared, and the weight of that loss is still deeply felt by her family, her friends, and this entire community,” Kane County State Attorney Jamie Mosser said.

“My heart remains with all who continue to carry that pain. We have not forgotten Kianna, and we remain steadfast in our commitment to seek the truth.

“It is my hope that renewed efforts will finally bring the answers her family deserves.”

A neighbor said he saw Galvin go into the house on the day she was last seen – May 6, 2016.

Galvin told her sister she was going to the Jim Hansen Park before messaging a man at around 12.30 p.m., letting him know she was on her way to his house to buy marijuana, the Daily Herald reported.

Just 40 minutes later, her cell phone was cut off, and there were no further calls or texts from her.

One neighbor spotted blood spatters on a garbage can lid six days later – and testing concluded it belonged to Galvin.

Cops carried out a search at the property in the November of that year, but didn’t reveal what, if any, evidence was found.

There have not been any charges in connection with Galvin’s disappearance.

Galvin’s mom, Fiona, described her daughter’s disappearance as her “worst nightmare.”

“It was Mother’s Day,” she told WLS at the time. “We had plans. She was gonna cook out steaks we had just bought the day before she went missing.”

Galvin left her purse and wallet at home before vanishing.

In 2020, Fiona said her daughter’s case was a homicide, the Daily Herald reported.
