TULSA, Oklahoma - Paul Ferrante's daughter, Kayla, was murdered May 26 and no one has been arrested.

Tulsa detectives can't find any reason Kayla would've been a target.

Kayla's parents were divorced when she was a toddler.

She and her dad spend most weekends together and those were the most treasured moments of his life.

It's hard for him to accept she's gone and in such a seemingly random, senseless way.

Paul shared some of his favorite memories of Kayla as he thumbed through pictures of their time together, whether it was trying on funny hats and sunglasses while waiting on a movie or hanging out in the park.

It's hard for him to fathom she is gone and keeps a part of her close.

"She's with me," Paul said. "I've actually got some of her ashes, so I've got her with me all the time."

Kayla graduated high school a year early, at age 17, on Friday, May 25th.

She'd gone to her grandmother's the next afternoon for her family celebration, then to a friend's house.

Her boyfriend was bringing her home, when someone fired shots from a high-powered rifle and one of the rounds hit Kayla in the car.

She and her Dad said "I love you" each and every time they talked, and her last day was no different.

"The last thing I said to her at my mom's party that day, we gave each other a big hug and said we loved each other, and that was the last time I saw her," Paul said.

Paul believes someone knows what happened and can't imagine why they haven't called police.

He'd like to why it happened, but realizes there is no reason good enough that his little girl, the light of his life, was killed.

He had to see her one final time, just to convince himself she was truly gone.

"I don't do viewings, haven't been to one in my entire life because I don't like them, they're uncomfortable," Paul said, wiping away tears.

"I forced myself to do it, because I couldn't believe it, it's not, wasn't real. I had to see."

Police say a tan or white, four-door, sedan-type car was seen speeding from the area after Kayla was shot, and they need any tips they can get.

If you know anything about the crime, you can call Crime Stoppers at 918-596-COPS.

Kayla would've been enrolled at TCC now and Thursday would've been her first day to volunteer at Little Lighthouse. Her passion and career choice was to work with children with disabilities.
