Update, 6:19 p.m., Sunday, July 3

Police have identified a 42-year-old man as the suspect in a kidnapping, sexual assault and shooting that spurred a manhunt Friday morning.

Anthony David Stone should be considered armed and dangerous, Sgt. Pete Simpson, a Portland police spokesman, said in a news release.

Stone doesn't have a local address, and police don't know why he's in Portland. He's 5-foot-9 and 230 pounds.

Stone "has a significant and violent criminal history on the East Coast," Simpson said.

Detectives were told Stone threatened to engage police in a shootout, Simpson said. Simpson said Saturday morning that detectives aren't currently sharing how Stone was identified as the suspect.

Police have obtained an arrest warrant for Stone on an accusation of kidnapping, Simpson said.

Investigators tied Stone to the Friday morning kidnapping, sexual assault and shooting of a woman who was forced into a car while she was walking on a street in Southeast Portland, police said.

The manhunt disrupted traffic through the morning rush hour, with the Hawthorne Bridge closed for about five hours and the Morrison Bridge for an hour.

The incident began about 2:25 a.m. after East Precinct officers responded to reports of a kidnapping at Southeast 88th Avenue and Powell Boulevard in the Lents neighborhood, Simpson said. Officers learned a man had abducted a 41-year-old woman at gunpoint while she walked with a male companion, he said.

The suspect had pulled his car to the curb, got out with a gun and demanded that the woman get inside, then sped away, Simpson said.

Moments later, officers spotted a car matching the description of the suspect's at Southeast 92nd Avenue and Holgate Boulevard, Simpson said. The car headed west at high speeds.

At 3:56 a.m., officers responded to a shooting at Southeast 43rd Avenue at Woodward Street in the Richmond neighborhood, where they found the abducted woman. She had been shot but was expected to survive, Simpson said. She told police her captor sexually assaulted her, Simpson said.

Ten minutes later, officers responded to a report of a crash on the westbound lane approaching the Hawthorne Bridge west of Southeast Martin Luther King Jr. Boulevard.

Witnesses told officers that a man got out of his car, shot at it and then ran toward the Willamette River and downtown. About two dozen police cars converged on the scene, including members of the Special Emergency Reaction Team and the Crisis Negotiation Team. They closed several streets and Waterfront Park, including the Blues Festival area.

Police later determined that the man never crossed the Hawthorne Bridge after they reviewed surveillance footage from the bridge, Simpson said. Instead, they learned the man ran off the north side of the Hawthorne Bridge toward the Eastbank Esplanade, he said.

"The behavior that has been described to us -- where he crashes his car, shoots his own car and then runs away -- is certainly not something we generally see," Simpson said. "So we're obviously concerned about where his mental state is at or whether he's under the influence. We just don't know enough yet."

Stone has a criminal record in Connecticut, according to The Hartford Courant He most recently was convicted on Oct. 29, 2014, in Superior Court in Hartford, and sentenced to 10 months in prison after being convicted of third-degree assault.

On Aug. 11, 2009, Stone was sentenced in Connecticut to 37 months in federal prison for possession of a firearm by a convicted felon. Before that, Windsor police charged him in 2007 with trying to abduct an 18-year-old woman at the Windsor Shopping Center. Other past offenses include sexual assault of a 15-year-old girl and domestic violence, The Courant reported.

Police asked anyone with information to call Detective Brad Clifton at 503-823-0696 or email him at brad.clifton@portlandoregon.gov, or Detective Rico Beniga at 503-823-0457 or email him at rico.beniga@portlandoregon.gov.

Anyone who sees Stone should call 911. This post will be updated as news develops.
