FERGUSON, Mo. (AP) — Crews erected barricades around the building where a grand jury has been considering whether to indict the Ferguson police officer who shot and killed Michael Brown, even as a grand jury decision seemed unlikely this weekend.

Tension has been mounting in Ferguson and elsewhere in the St. Louis area in recent days, with many speculating that the grand jury’s decision would be announced on Sunday. That seemed increasingly unlikely by late Saturday, although there was a noticeable uptick in the preparations being made.

Downtown STL Inc., a St. Louis civic group that promotes downtown businesses, told members in an email Saturday that the grand jury will reconvene Monday to continue deliberating whether charges are warranted against Ferguson police Officer Darren Wilson in the Aug. 9 fatal shooting of Brown.
