CITRUS COUNTY, Fla. — Citrus County deputies say they have made an arrest in the murder of 57-year-old Denise Hallowell.

Deputies say her son, Carlos Hallowell, 17, called 911 after he said was woken up from his sleep by the dogs barking. He told deputies he discovered his "mother's brutally murdered body," according to a news release.

However, investigators say he lied back on July 13, and after nine weeks of investigating and collecting evidence, Carolos was arrested for first-degree premeditated murder.

"No two cases are ever the same and this particular case had many unique technological challenges making it one of a kind," Sheriff Mike Prendergast said in the release. "The tireless work of our High Tech Crimes Unit and the assistance of The United States Secret Service, brought the much needed hidden digital evidence to the forefront paving the way for the arrest."

Patrol units, crime scene specialists, major crimes unit, dive teams, high tech crimes unit, secret service, the state attorney's office and Citrus County residents worked together to allow deputies to make an arrest.

"Justice has been partially served today and only when Carlos is finally convicted for his despicable actions, will we be satisfied," the news release ended with.
