EXCLUSIVE: The sister of slain New Jersey therapist Brooke Hanlon said her family is dealing with “a complete nightmare” after the young mom was found fatally stabbed inside her home in an affluent New Jersey community.
Hanlon’s sister spoke exclusively with Fox News Digital one month after the attack, which is still under investigation as authorities hunt for a suspect.
It has been exactly one month since 35-year-old new mother was found dead in her Chester home. Investigators have not yet named a suspect in the June 6 killing.
“Brooke was the sweetest, purest person that I have ever known in my entire life,” said Paige Haggerty, Hanlon’s sister. She went on to say, “Everything that I know, I have learned from her. I’ve never lived without her. She taught me everything.”
