Courtney A. Sherman, 18, of Fox Lake, was in the passenger seat and the oldest of the teens

Three teenage girls are charged in connection with the death of a father of seven over an iPhone.

An 18-year-old and two unidentified 17-year-olds were charged with reckless homicide and robbery.

The oldest, 18-year-old Courtney A. Sherman, of Tweed Road in Fox Lake, Illinois, was a passenger in a carload of five teen girls who met (Trinidad) Javier Bueno-Sanchez, 43, in a Meijer store parking lot in Round Lake Beach at 7:55pm on April 24, according to The Chicago Tribune.

Javier Bueno-Sanchez, above left with his children ranging in age from 27 to six, was killed when five teen girls took off in their car as he was negotiating with them to sell his iPhone

The father of seven was said to be involved in all of his children's activities. 'He was such a good person,' said daughter Lily Olmos

The teen girls contacted the dad through the Offer Up app and had agreed to buy an iPhone 6 from the dad for $450.

Police said Bueno-Sanchez conducted the sale while the girls sat in their car in the parking lot. When Sherman, who was in the passenger seat, handed him an envelope with cash in it, he quickly realized it was only a few dollars, not the $450 they'd agreed to.

Bueno-Sanchez left behind a wife, seven children, and four grandchildren in Illinois

When he tried to get his phone back, the 17-year-old driver allegedly took off, with Bueno-Sanchez clinging to the car.

'At that point, when he realized that and that girls realized that he was on to them, they sped away,' Round Lake Beach Police Chief Michael Scott told WLS.

The car dragged him until he fell to the pavement, smacking his head. The suspects then fled the scene, said police.

The victim was conscious when help arrived and at first he was talking and it didn't seem as if his injuries were serious, said Scott.

The teen girls met the father of seven in this parking lot Round Lake Beach around 7:55pm

But within a few hours, things took a turn for the worse and he died three days later.

Lake County Coroner Dr. Howard Cooper ruled his death a homicide caused by head trauma.

Two other teens in the car, a 16 and 17-year-old, will not be charged.

Bueno-Sanchez had seven children, ranging in age from 27 to six.

Family describe him as a very active dad who was involved in all aspects of his children's lives.

'He was such a good person, he didn't deserve any of this,' daughter Lily Olmos told WLS.

'To realize this has happened over a cell phone and that the people who did were teenage girls,' said family friend Tina Rompala.

He is also survived by his wife and four grandchildren.

Sherman is being held on $500,000 bond. The other two unidentified teen girls will likely be charged as adults, said Smith.

Scott said that, tragically, the dad had taken all the right precautions for the sale, meeting the girls early in a well-populated area, and not getting in their car, but he still ended up dead.

'Young people don’t think of the ramifications of their actions,' Scott told Fox 40. 'They think of what they’re planning on doing and they don’t think of the things that can go wrong … with this, everything that could have went wrong did, and it can’t get more serious than it is right now.'
