Pasco County Sheriff Chris Nocco says they still don't know what led to a fight between a group of brothers that ended with two of them dead and another one in the hospital.

At a press conference Thursday morning, Nocco released the names of the brothers: Trevor Pimentel, 16; Kevin Pimentel, 12; Brady Pimentel, 6. He said Kevin would've turned 13 at the end of this month.

Nocco said initially they believed the fight was over food but now say Trevor and Kevin were preparing food at the time an argument broke out.

Deputies received the call at 6:19 p.m. from a mobile home in the 16000 block of Bachmann Avenue in Hudson.

"Sixteen-year-old Trevor called 911, telling the dispatcher his brother, Kevin, 12 years old, had just shot Brady, 6, then shot himself," Nocco said.

A deputy arriving on scene heard a boy screaming and he charged into the house, Nocco said.

“He hears, as it turns out it was actually Trevor, 16-year-old Trevor inside screaming, I’ve been shot, I’ve been shot,” Nocco said.

Trevor was transported to a local hospital with a non-life threatening gunshot wound to the leg, according to deputies.

The boys' mother, Helen Campochiaro, was at work at the time. Nocco described her as hard-working, noting she has two jobs and was recently in a car accident but chose to keep working.

Two days ago, she started a gofundme page asking the public for help saying she’s had to deal with divorce, theft, abuse, and that she had to sell almost everything she owns to make life better for her boys.

Still many questions remain. Investigators have not released who the gun belonged to or why it was in the home.

Investigators have been trying to talk to family but the tragedy has made it impossible at this time.

“When our detectives were talking to Trevor his heart rate would actually go to 185, Nocco said. “Anybody knows medically that is extremely dangerous, he’s grieving right now.”

An 18-year-old brother who also lives at the home also was not at the residence at the time of the shooting.

Brady attended Hudson Elementary School, Kevin went to Hudson Middle School and Trevor attended Hudson High School in the mornings through virtual education classes, according to Superintendent Kurt Browning.

Crisis teams will be at the elementary and middle schools "as long as we need to," Browning said. "It's very tragic but we are working to heal families and students."

Browning said Trevor attended Marchman Technical College's culinary program in the afternoons.

Campochiaro’s friend and neighbor, Kara Butz said her son would hang out at the home and he never saw the children fight.

“I asked him several times what was it like over there did you ever hear fighting? He said no they played, the brothers played with the brothers, my son would never feel comfortable in a house that fought,” she said.

Neither DCF nor the Pasco County Sheriff's Office Child Protection Investigation Unit has had prior contact with the family.
