PHILADELPHIA (WPVI) -- Family members of the 7-year-old girl who was killed by her father in a Philadelphia murder-suicide last month are talking about the pain caused by the horrendous act.

"I miss talking to her, I miss holding her hand and I miss kissing her in the morning, and good night, and waking up in the morning and kissing her," said Kathy Sherlock, the mother of 7-year-old Kayden Mancuso, in an interview aired on ABC's Nightline at 12:35 a.m. Thursday on 6abc.

"I miss her little voice. I miss every single little thing about her."

Jeff Mancuso killed Kayden, his daughter, amid a contentious custody battle. Their bodies were found in a home on Wilde Street in the Manayunk section of the city.

Family and friends remember girl killed by her father as reported during Action News at 11 on August 7, 2018.

Kayden lived most of the time with her mother in Bucks County and would have been entering 2nd grade at Edgewood Elementary in Morrisville.

"She knew she was liked, but the outpouring of love that she has received, I don't think she would've believed me if I told her," Kathy said.

"I'm going to miss having a catch out back," said Kayden's stepfather, Brian Sherlock. "She'd keep me out there until the sun went down, you know? And that was that 'one more time,' you know? One more time was 50 more times," he said. "That's the stuff I'm going to miss."

Jeff Mancuso's sister, Allyson, said she will never forgive him.

"I wish he'd rot in hell for what he did," she said.

Watch the report from Dann Cuellar on Action News at 10 p.m. on August 6, 2018.

Family members say Kayden was dropped off to be with her father for the weekend on Saturday and was due back on Sunday.

The child's stepfather made the grisly discovery on Monday morning.

Engaged in a fierce and prolonged custody battle, a mental health evaluation ordered by a judge in the Bucks County Domestic Relations Court concluded that Jeff Mancuso suffered from a major depressive disorder - a man filled with hopelessness and suicidal tendencies and a long history of violence.

A judge concluded that the father's history of violence - including punching the family dog - and his lack of personal responsibility and remorse, had substantially and adversely affected his relations with his daughter. Still, he ordered that Mancuso be allowed custody of her, but only from 10 p.m. Saturdays to 6 p.m. Sundays.

Family members are set to meet with Pennsylvania Governor Tom Wolf on Friday, where they will push for "Kayden's Law" to protect other children
