Police said they received a dozen calls in all.
Officers interviewed dozens of potential witnesses into the morning, and shut down Route 108 near the Manorstone Lane intersection hours as they investigated the second Howard homicide of the year. The first took place in August, when police said an assisted-living-facility patient suffering from dementia beat a fellow resident to death.
The scene evoked memories of a 2005 incident in Anne Arundel County, where two National Football League teams rented a mansion in a residential neighborhood in Gambrills for a 400-guest party that ended in a non-fatal shooting. Neighbors of the property had earlier complained that the owners of the house were running an unauthorized nightclub where admission was charged. A judge issued an injunction preventing additional events.
