The Clark County coroner's office ruled Tuesday that 25-year-old professional golfer Erica Blasberg's death was a suicide.

Blasberg died May 9 at her home in Henderson, about 15 miles southeast of the Las Vegas Strip. She was found with a plastic bag secured over her head.

Henderson police said that while no foul play is suspected they have issued a misdemeanor arrest warrant for Dr. Thomas Hess on obstruction charges. Police said Hess, who discovered Blasberg's body, removed items from the scene, including a suicide note.

The contents of the note haven't been disclosed.

Hess turned himself into authorities, was booked into jail and released about 35 minutes later, after posting $637 in bail Tuesday afternoon, Henderson police spokesman Keith Paul said.

David Mincavage, an assistant city attorney in Henderson, said the nonviolent misdemeanor charges against Hess carry a maximum penalty of a $1,000 fine and six months in jail.

Mincavage said he could not comment further on the case, and Paul declined to say whether additional charges were possible.

The coroner's office said Blasberg died of suicide due to asphyxia, coupled with the presence of toxic levels of prescription medication in her system, including prescription headache, cough, pain and anti-anxiety medications.

The drugs in Blasberg's system included butalbital, temazepam, alprazolam, codeine, hydrocodone, and tramadol, according to the coroner, but Nevada law doesn't permit the release of details on the amounts of medication.

Nearly four months after LPGA golfer Erica Blasberg was found dead in her home, the investigation into what caused her death is finally coming to a close.

Dueling divas in the world cyber. Has Lady Gaga left Britney Spears "Speechless"? Britney's reign as Twitter queen has come to an end thanks to fellow pop superstar Lady Gaga, Access Hollywood has confirmed. Nearly three-months after Britney usurped the most-followed Twitter user crown from Ashton Kutcher, the pop singer lost the title to Lady Gaga. On Saturday, Gaga surged into the lead, netting 5,694,147 followers to Brit's 5,685,390 -- a difference of nearly 9,000 users.

The Fierce & Fabulous Fashion-Forward Looks Of Lady Gaga

The singer broke from her usual "Poker Face" after learning the news, posting a Twitpic of herself with the rock band KISS, and Tweeting, "KISS the Queen," followed by the trending topic, "#GagaTwitterQueen."

As for Britney, her account remained silent, the last message having been posted on Aug. 19, when she visited the set of "Glee."

The battle wasn't a quick one, however. According to People, on Friday there was a back and forth for the top spot on the social networking website. At first, Gaga's "little monsters" (her nickname for her fans), appeared to help the singer "Just Dance" her way into the top spot, but Britney regained the crown "One More Time." On Saturday morning, the "Lucky" singer's luck though, ran out.

Gaga also reportedly leads the "Love Game" on Facebook with more than 16 million friends, beating both Britney and President Obama.

The Twitter "Circus" might not prove to be too "Toxic" for Britney, who may heat up again on the website's "Radar" after her highly-anticipated "Glee" episode debuts on Sept. 28 on FOX.
