ANCHORAGE, Alaska - -

The man accused of killing two teenage girls in Anchorage last week has been indicted by a grand jury with two counts of second-degree murder, two counts of manslaughter and driving under the influence, according to the Department of Law.

Stacey Allen Graham, 31, is accused of causing an Aug. 9 crash on Abbott Road that resulted in the deaths of 15-year-olds Brooke McPheters and Jordyn Durr.

APD traffic investigators claim that Graham was driving his red 2006 Toyota Tacoma pick-up truck east on Dimond Boulevard, toward Abbott Road, in "a reckless manner and at a high rate of speed," based on witness statements.

"Preliminary alcohol tests indicate Graham was approximately three times the legal limit at the time of the crash," said APD spokeswoman Dani Myren at the time of the crash.

Previously, there were questions about what charges Graham should face, murder or manslaughter, crimes that are similar under Alaska statutes.

At the news of the grand jury indictment, the families said they are committed to achieving justice for their "beautiful angels.

"We appreciate the continued support of the community and all efforts to stop the devastating problem of drinking and driving in our city," the family said in a written statement. "We encourage all residents to be REDDI (reporting every dangerous driver immediately)."

If convicted, Graham faces a sentence of up to 99 years in prison and a fine of $500,000
on each murder count.

Graham was appointed a public defender following his first appearance in court. His bail is set at $100,000.
