High said this week that county narcotics officers, who were tracking the shipment and who had obtained a search warrant, did not know the home belonged to the mayor and his wife. The sheriff's department, which provided its SWAT team for the raid, also apparently had not attempted to use nonlethal force, such as fire extinguishers or pepper spray, to subdue Calvo's two black Labrador retrievers.

The sheriff offered new details about the raid, saying that his deputies were briefed on the layout of the home and that they knew there were dogs inside.

An attorney came forward yesterday to allege a possible pattern of animal abuse by the sheriff's department. Michael Winkleman said he is representing another family whose dog was shot by sheriff's deputies in November, along with a woman who is suing the department for searching her home without a warrant and threatening to shoot her dog.
In the first case, Winkleman said, sheriff's deputies arrived at the Accokeek home of Frank and Pamela Myers with a warrant for another house on their street. After the couple informed the deputies of their error, they continued to question the couple and looked around their home.
As they spoke, the couple's 5-year-old German boxer began barking in a yard, out of sight. Soon after, according to Winkleman, the couple heard gunshots, and they found the dog shot to death. He said the family is preparing to file suit.
In another case, Upper Marlboro resident Amber James has filed a $4 million lawsuit accusing sheriff's deputies of searching her home without a warrant in May 2007 while looking for her sister, who lived in Capitol Heights. According to the suit, deputies falsely claimed to have a warrant and searched every room of the home. When they did not find the sister, the suit alleges, they threatened to return the next day and search again, saying that if they did, James's dog would be dead.
