ATLANTA (CBS News) ― Investigators are looking into who altered pro wrestler Chris Benoit's Wikipedia entry to mention his wife's death hours before authorities discovered the bodies of the couple and their 7-year-old son.

Benoit's Wikipedia entry was altered early Monday to say that the wrestler had missed a match two days earlier because of his wife's death.

A Wikipedia official, Cary Bass, said Thursday that the entry was made by someone using an Internet protocol address registered in Stamford, Conn., where World Wrestling Entertainment is based.

An IP address, a unique series of numbers carried by every machine connected to the Internet, does not necessarily have to be broadcast from where it is registered. The bodies were found in Benoit's home in suburban Atlanta, and it's not known where the posting was sent from, Bass said.

Also Thursday, federal drug agents and sheriff's officials raided the office of pro wrestler Chris Benoit's personal physician in search of records and other items, an official said.

The raid at Dr. Phil Astin's office in Carrollton began Wednesday night and concluded early Thursday, said agent Chuvalo Truesdell, a spokesman for the Drug Enforcement Administration in Atlanta.

A search warrant obtained by the Fayette County Sheriff's Department in connection with the Benoit investigation was executed there, he said.

No arrests were made and Truesdell was unable to say what was seized. He said records were among the items being sought, but he could not be more specific.

Astin did not return repeated calls to his cell phone from The Associated Press on Thursday.

Benoit had been under the care of Astin, a longtime friend, for treatment of low testosterone levels. Astin said Wednesday the condition likely originated from previous steroid use.

Astin prescribed testosterone for Benoit in the past but would not say what, if any, medications he prescribed when Benoit visited his office Friday.

Over the weekend, Benoit killed his wife and son and then killed himself at their home in Fayetteville.

Anabolic steroids were found in Benoit's home, leading officials to wonder whether the drugs played a role in the slayings. Some experts believe steroids cause paranoia, depression and violent outbursts known as "roid rage."

But World Wrestling Entertainment owner Vince McMahon on Thursday cautioned against assuming that steroids played a role in the murder-suicide of pro-wrestler Chris Benoit, his wife and 7-year-old son.

McMahon said toxicology results were needed to answer questions surrounding the death of Benoit, who hanged himself on the cable of a weight-machine in his home this week. Authorities said he strangled his wife and smothered his son over the weekend and placed Bibles next to their bodies.

"There's no way, quite frankly, that we, or the media — it's all speculation until the toxicology reports come back," McMahon said, speaking on a morning talk show. "It's all speculation."

The WWE, based in Stamford, Connecticut, was quick to dismiss the idea that steroids played a role, issuing a news release Tuesday saying they "were not and could not be related to the cause of death" and that the findings indicate "deliberation, not rage." Benoit tested negative April 10, the last time he was tested for drugs, the WWE said.

Toxicology test results may not be available for weeks or even months, District Attorney Scott Ballard has said.

No motive has been offered for the killings.

The couple argued in the days before the slayings over whether he should stay home more to take care of their mentally retarded son, said Jerry McDevitt, an attorney for the league.

McDevitt said the wrestling organization learned from the couple's friends and relatives that the Benoits were struggling with where to send the boy to school since he had recently finished kindergarten.

He also said Benoit's wife did not want him to quit wrestling, but she "wanted him to be at home more to care for the kid. She'd say she can't take care of him by herself when he was on the road."

The child suffered from a rare medical condition called Fragile X Syndrome, an inherited form of mental retardation often accompanied by autism, McDevitt said.

Meanwhile, authorities in Georgia were investigating a link between Benoit and a Florida business that may have supplied him with steroids.
Prosecutors in upstate New York who have been investigating the company's drug sales said Benoit received deliveries from Signature Pharmacy and MedXLife.com, which sold steroids, human growth hormone and testosterone on the Internet.

Six people, including two of the pharmacy's owners, have pleaded guilty in the investigation, and 20 more have been arrested, including doctors and pharmacists.

Terence Kindlon, lawyer for MedXLife co-owner Dr. Gary Brandwein, denied the allegations that his client's company sold steroids to Benoit.

Brandwein has pleaded not guilty to six counts in New York state court related to the criminal sale of a controlled substance. He was accused of signing and sending prescriptions without ever seeing patients.

McDevitt said the drugs found in Benoit's house were legitimately prescribed.

"There's no question, none of these drugs are out there, none of these drugs came from Internet pharmacies," he said.

In addition to causing paranoia and explosive outbursts, steroids can also contribute to deep depression, according to experts.
