According to two law enforcement officials, Clark Rockefeller's fingerprints, taken after his capture, were linked to an out-of-state license application under a different name, presumably yet another alias, the Globe reports. That name is on a list of people wanted in a homicide case in California, according to the officials.
"A fingerprint connected him to a license application, and an alias on the application connected him to a murder in California," one of the two officials told the Globe.
Authorities released no details of the crime, except to say it was committed more than a decade ago, the Globe reported.
An attorney for Rockefeller said Tuesday the man did not kidnap his own child, nor does he have any link to a California slaying.
Stephen Hrones told reporters that Clark Rockefeller is not guilty of abducting Reigh Boss.
"How could you kidnap your own daughter?" Hrones said. "He loves his daughter. Kidnapping doesn't apply, it was his own kid."
Hrones also denied a report in The Boston Globe that Rockefeller's fingerprints may be linked to a slaying investigation in California.
On Tuesday, Rockefeller arrived in Massachusetts to face arraignment. He landed at Logan Airport at about 10 a.m. and was whisked away by law enforcement officials.
A Suffolk District Attorney's Office spokesman says Rockefeller will be booked and processed and is expected to face arraignment later Tuesday.
Police say Rockefeller, who has multiple aliases, abducted his 7-year-old daughter, Reigh Boss, July 27 on a supervised visit. Police apprehended him Saturday in Baltimore, where he had purchased a house and boat. He faces charges of felony parental kidnapping, assault and battery and assault and battery with a dangerous weapon.
When Sandra Boss was told that her little girl was found safe and sound, "she collapsed into my arms. She was overjoyed," a Boston Police deputy superintendent said Monday.
Thomas Lee, speaking to CBS' The Early Show, called it "one of the most rewarding moments in my police career."
Boston police told the Boston Globe that it appears Rockefeller was setting up a new life in Baltimore at the time of arrest.
The seller of a home Rockefeller bought for $450,000 cash a month ago says he called himself Chip Smith and mentioned his daughter was coming to live with him.
"We understand his boat has been down there at least two years and he had been traveling in the area for some time over the last year," Lee told The Early Show.
Authorities are still trying to determine his real identity after they uncovered additional aliases he used in Maryland.
