Now that the parents of Annie McCann have gone public with concerns about how their daughter's death case has been handled by Baltimore authorities, information is starting to filter out -- and it's causing even more pain for the family.

Annie, 16, ran away from her suburban Virginia home on Oct. 31 and was found dead in Southeast Baltimore on Nov. 2. She left a note saying she had considered suicide but changed her mind and wanted to get away instead. She left other notes with suicide as a theme but had crumpled them up and thrown them under her bed.

Her parents, Daniel and Mary Jane, held a news conference yesterday raising numerous concerns about the police investigation and their inclination to call the death a suicide. The parents feel there are too many lose ends to come to that conclusion.

Among them are the cause of death. The McCanns had told me, based on conversations with police and the Medical Examiner's Office, that Annie had died from an overdose of lidocaine, an ingredient in the disinfectant Bactine. She drank from a five-ounce bottle of the over-the-counter medicine. The only alcohol in her system was a small amount that the body produces when it decomposes.

I had confirmed that with the lead Baltimore Police Department homicide detective, Sean P. Jones, and the head of the homicide unit, Maj. Terrence McLarney. But it turns out that police learned later that the Medical Examiner found additional amounts of alcohol.

Police spokesman Anthony Guglielmi told me they learned of this late Friday and even they have not yet obtained a copy of the autopsy report. He did not have the blood-alcohol content but he told me it was consistent with a light amount of drinking.

I could not confirm that with the Medical Examiner -- they refuse to release the report until the case is officially closed by both police and prosecutors, which is unlikely anytime soon because the cause of death has been ruled undetermined, which means it remains open until police either make an arrest or conclude the case for some other reason.

The information about alcohol also came as news to the McCanns. They have been talking to detectives and hired private investigators, only to find out new and painful information from reporters stemming from leaks -- the alcohol was first reported by WBAL-TV -- that could be coming from investigators privately frustrated that the McCanns have criticized them in public.

It does seem odd that after months of being told by police and the medical examiner's office that there was no new news on the death of Annie, that it was still under investigation and toxicology reports pending, that on the very day the McCanns made their intent known to go public with their complaints, and hours after I talked with the lead detective, that the Medical Examiner suddenly released his conclusions that Annie overdosed from lidocaine.

For a father trying to learn what he can about his daughter's death and trying to push authorities to do their jobs, this news was particularly maddening. Mr. McCann sent this response:

"Four months after a reportedly exhaustive autopsy on our daughter, we would be astonished to learn – if true – that toxicology results indicate Annie had been drinking alcohol. This would directly contradict results, as consistently characterized to us for months. We find it hard to believe that there has been a new finding with respect to blood-alcohol content – or with any other simple, static, objective, and quantifiable data."
