Prosecutors say a Union County man and his adult daughter were killed in their home.

The investigation is ongoing Tuesday after Springfield Township police on Monday responded to a request to check on 79-year-old Thomas Brown and his 51-year-old daughter, Roth.

Officers found them stabbed to death in the home on Meckes Street.

Prosecutors are offering a reward of up to $10,000 for information leading to an arrest and indictment in the case.
