JACKSONVILLE, Fla. -

No charges have been filed yet against the man who police say drove a minivan through a teen's bedroom last week.

Detectives say they are waiting until blood alcohol content results comes back for Ismet Sijamhodzic, who police said drove through 17-year-old JaNay Jackson's room, killing her. The Florida Department of Law Enforcement said the final toxicology results could be complete within the next few days or could take weeks, and they've already given investigators preliminary results.

Once the results are finalized, investigators said they can determine whether alcohol was a factor in the crash or if Sijamhodzic had a medical condition.Ismet Sijamhodzic

In the week since Jackson's death, her family says they've been waiting for answers.

"My daughter is lying here dead, and he's walking around? I don't understand that," said Felicia Jackson, JaNay's mother.

That was Felicia's response when Jacksonville Sheriff's Office detectives told her the man they said drove a minivan into her daughters room had been treated and released. She found out in the hospital just minutes after her daughter was pronounced dead.

For JaNay's father, Jerry Jackson, the pain cuts deeper when he thinks about seeing him in her room after the crash.

"I'm screaming at him because I open up the back of the van and he's just sitting there," Jerry said. "And he just turns and just looks at me. I mean, just expressionless."

Police said Sijamhodzic was taken to a hospital, where his blood was drawn for a toxicology report. From there the FDLE took over, analyzing the sample in its lab.

"There's not just one test that you can perform that will give you a readout of possible alcohol or drugs in the system," FDLE spokeswoman Gretl Plessinger said of why the process takes so long. "You have to perform each test separately."

For the Jackson family, their memories of JaNay that night make it hard to wait for the results.

"I turned and I looked at her and I saw -- all I could see of her was her head to her waist and nothing else," Felicia said. "I would have never guessed while she's in her haven peacefully in her home, while she's asleep, that what happened happened."

Police said they are still investigating the crash to see if speed was a factor. Once the FDLE releases its results, police will decide what charges, if any, will be filed.

Meanwhile, JaNay Jackson's funeral will be held at 5 p.m. Saturday at Hardage-Giddens Funeral Home on Hendricks Avenue.
