Tips from the public on last week's attempted bombing of the Jackson County District Attorney's Office are pouring in, but authorities say they have yielded little new concrete information.
"We can't talk about the intricate details," said Lt. Mike Budreau of Medford police.
So far, local and federal investigators have received dozens of tips from the public. Investigators continue to look for a black or dark-colored, two-door sports car with a convertible top seen in the area during the incident. Additionally, they hope to track down an unidentified man with a flashlight seen fleeing eastbound on Eleventh Street, and another who fled from officers when spotted at the corner of Columbus Avenue and Tenth Street.
"It's really hard to say what's going on with that," Budreau said.
Looking for homes with video home security systems has been a dead-end thus far.
"We're still trying to find good evidence of home security video in the neighborhood, and we haven't had a lot of success," Budreau said. "We're always holding out a little bit of hope it could be there."
An explosion was reported at 4:38 a.m. Nov. 13 outside the DA's office, 715 W. 10th St., Medford. An improvised explosive device attached to a propane tank detonated, blowing out several windows on the front of the building and awakening neighbors. But the propane tank itself did not explode as intended, authorities said.
Police roped off the surrounding area for most of the day, combing the neighborhood for evidence. The DA's office temporarily worked with a bare-bones crew and had to cancel some grand jury sessions and delay court hearings. The facility reopened Thursday afternoon.
"All court appearances and everything like that are back to normal schedule," said Jackson County District Attorney Beth Heckert.
Heckert said the office had not received any threatening calls or messages since the incident.
"It makes you a little apprehensive," Heckert said of the ongoing investigation. "But for the most part everyone's getting back to work and trying to catch up and trying to get back to the work that we missed."
Investigators from Medford police, the Jackson County Sheriff's Department, the Oregon State Police Bomb Squad, the FBI, and the Bureau of Alcohol, Tobacco, Firearms and Explosives continue to work the case. Police believe the bombing is not related to arson fires set in 14 vacant homes in west Medford since January 2012.
"Arsonists, they keep doing what they're doing because it works," Budreau said, adding the attack against the DA's office was an intentional targeted attack. "(The arsonist) is starting fires because he likes starting fires."
No group or individual has claimed responsibility for the bombing.
Anyone with information about the case is asked to call Medford police dispatch at 541-770-4783.
