A woman was stabbed near the Washington convention center late Friday night, authorities said.

The stabbing occurred about 11:15 p.m. near 7th and M Streets NW, which is near the center and the Mount Vernon Square Metro station..

According to initial reports, the woman was stabbed in or near her jaw. She was conscious and breathing, authorities said.

Police said they were looking for two women in connection with the incident. No motive could be learned immediately.

Christopher Chamblin was convicted by a jury late Friday of 10 sex-related offenses stemming from allegations that he raped two young neighbors more than 30 years ago in Silver Spring.

Chamblin, 49, who had been living in South Florida, faces up to three life sentences for each of the three first-degree rape convictions, according to prosecutors. The crimes stretched over several years, when he was between 14 and 16 years old, and when his two victims, who are sisters, were between 5 and 9 years old, said John Maloney, a Montgomery County Deputy State’s Attorney.

The trial lasted a week. Sentencing is set for August.

“The state is quite pleased that this defendant is finally being held accountable for the suffering he inflicted on these innocent girls many years ago,” Maloney said.

A grueling day of technical DNA testimony Friday in the Roger Clemens trial ended on a grim note when U.S. District Court Judge Reggie Walton recessed the proceedings because a juror learned her mother had died.

Walton told lawyers that the juror, number 16, would check in with his clerk on Memorial Day, though it was likely she might be unavailable for the rest of the trial. He said the juror would have to head to Philadelphia to make funeral arrangements.

If the juror is not able to return, there would be only one alternate available, Walton said. Clemens is charged with perjury, making false statements and obstruction of Congress for denying that he ever used steroids or human growth hormone in his 2008 testimony before a House panel.

The sudden end to the proceedings Friday came about 4:30 p.m., and prosecutors had not yet rested their case — as some expected them to do. Their DNA expert, Alan Keel, had testified for several hours prior about DNA evidence that he said linked Clemens to a few cotton balls that his strength coach turned over to federal prosecutors.

Keel had also testified about a needle from the strength coach that possibly contained Clemens’ DNA — rejecting a defense attorney’s suggestion that someone might have planted biological evidence on it because the samples recovered were so small. That might help bolster the credibility of the strength coach, Brian McNamee, who came under vigorous cross examination earlier in the trial. Samples collected from that item would also match 1 in 449 people, according to testimony.

The trial is scheduled to resume 9 am Tuesday.

Attorneys for former University of Virginia lacrosse player George Huguely V of Chevy Chase have asked for a new trial, arguing that the trial judge’s decision to move forward with testimony after one defense lawyer was too ill to attend court for two days violated Huguely’s sixth amendment right to counsel of his own choosing.

The retrial request was filed Friday afternoon in Charlottesville Circuit Court and will be heard during a scheduled July 29 hearing. Huguely was convicted in February of second-degree murder in the May 2010 death of his ex-girlfriend Love and was sentenced by the jury to a total 26 years.

Barring a new trial, Huguely, now 24, is set for sentencing by Charlottesville Circuit Judge Edward Hogshire on August 30 when Hogshire can accept or reduce the jury’s sentence.

A 91-year-old man has died from burns after his clothes caught fire while he was cooking at a stove in the kitchen of his McLean apartment Thursday night, Fairfax County fire officials said.

Carroll Adams, who lived alone, succumbed early Friday morning after he suffered burns over 40 percent of his body, said Dan Schmidt, a spokesman for the fire department.

Firefighters responded to the scene in the 1800 block of Old Meadow Road around 9:40 p.m., but the flames had already been doused, Schmidt said.

“There was a neighbor who heard the man call for help,” Schmidt said. ”The neighbor put out the flames on the individual.”

Firefighters treated the man at the scene and then transported him to the burn center at Washington Hospital Center, where he died, Schmidt said.

The death marks the first fire fatality of the year in Fairfax County. There were no such deaths last year — a first in the history of the fire department.
