Jennifers' Law went into effect in Connecticut, and it's making it easier for domestic violence victims to get a restraining order.

The law was named after Jennifer Dulos, the New Canaan woman whose husband was accused of killing her, and Jennifer Magnano - who hid the psychological abuse from her husband until her slaying.

Elle Kamihira, who made a film about Magnano, also pushed for Jennifers' Law.

"There's fear, you know, at the root of all this," she says.

Attorney Michelle Cruz says the legal definition of domestic violence now includes what's called "coercive control."

"So, then her cellphone stops ringing. Then her house phone rings again. Then she gets text messages. And it's that constant pattern of just continually to, like, get her to respond to him," she says.

For Magnano's kids, the intimidation was real.

"He had a baby monitor that he would adjust to the frequency to pick up the phone calls so that he could listen in," says David Magnano, Jennifer Magnano's son.

"When mom did get to eat dinner, she always had to stand because he would eat at the island and there were only three seats," says Jessica Rosenbeck, Jennifer Magnano's daughter.

Since "coercive control" can be hard to prove, the next step is working with judges and attorneys.

"We're kind of where we were with 'stalking' in the '90s. Like, we kind of understood it wasn't right, but we didn't understand it was a crime," says Cruz.
