It was yellow leaves instead of yellow crime scene tape around the Jackson County District Attorney's office Friday.
"We've put in a lot of hours this week. This case at this point is our number one priority," said Lt. Mike Budreau.
In a press conference Thursday, Medford Police Chief Tim George shared photo's of two vehicles, one of which they believe was been involved in the bombing.
"We're looking for a smaller, newer type, black sports car with a convertible top. It's not necessarily a suspect vehicle but its certainly a witness vehicle," said George.
Police have been on the lookout for the vehicle since, but locating it is trickier than one would imagine.
"It's such a general description, we aren't pulling over every convertible sports car we see," said Budreau.
The police department has also been flooded with phone calls of possible leads.
While nothing has fallen into place yet, police are determined to put an end to the case and will be working until it's case closed.
