Heather Locklear DUI Investigation Winding Down

D.A. tells E! News he's hoping that the final reports will come in this week, and that a decision on charges should be made fairly quickly

Heather Locklear still has to wait and see. And we're not referring to whether or not she will be called upon to vamp up the new Melrose Place.

The investigation continues into the prime-time bombshell's Sept. 27 arrest on suspicion of driving under the influence and possession of a controlled substance in tony Montecito, Calif., meaning charges have still yet to be filed against the 47-year-old actress—if, in fact, charges are coming.

According to Santa Barbara Deputy District Attorney Lee Carter, as of Monday the investigation into her DUI bust is nearly complete, but he isn't sure how long it will take to review the report and make a decision about charges.

"I am hoping that the final reports will come in this week," Carter tells E! News. "Once the final reports come in, I will review the case for the filing."

"It's difficult to say how long it might take to review all of the evidence and make a filing decision," he added, "but it is usually done in a short period of time."

If Locklear had been charged at the time of her arrest, for instance, she most likely would have had a court date by Oct. 27.

But Carter told E! last week that it isn't "abnormal" that the investigation has taken awhile to come together.

The prosecutor also said that the results of Locklear's toxicology tests would not be made public by his office, so would only be available if the defense chooses to air the outcome. Or, the results would be entered into the public record if the case—should there be one—ever goes to trial.

On Sept. 27, California Highway Patrol officers arrested the former Spin City star after, responding to a call from a "concerned citizen" who saw her behaving erratically in a parking lot, they found her car blocking traffic.

Alcohol was ruled out, but the CHP said that officers determined her to be under the influence of some type of controlled substance.

Locklear, who spent four weeks in an Arizona rehab facility to treat anxiety and depression, was released from custody later that night on $5,000 bail.
