On Friday, March 17, Palczynski penetrated a barrier and reached nearby
Dundalk, Maryland, going to the home of Tracy Whitehead's mother Lynn, her boyfriend Andrew McCord, and their 12-year-old son, Bradley McCord. Bradley let him into the house, as he did not understand the danger Palczynski posed. For the following 97 hours, nearly four days, Palczynski held the family hostage in their home, ignoring the requests of law enforcement and negotiators to release them, and occasionally firing shots. During the standoff, no one was permitted to enter the neighborhood of the hostage situation, an area that police defined as an "inner perimeter". All area residents were asked to stay at a shelter that was set up at a nearby
elementary school. Several people who violated the police perimeter were arrested. The Baltimore County Tactical Squad requisitioned a nearby house, in which there was a barking dog. The Tactical Squad shot and killed the dog. Palczynski made one demand to officers throughout the ordeal: to speak with Whitehead. Police denied this request. Afterward, they justified their decision, saying that it was his only request, and they feared that if they granted it, he might have killed Whitehead's mother and the other hostages while Tracy listened on the phone. Later it was reported that he also wanted to speak with his own mother, Pat Long, and Contrino. During this time, police kept Whitehead at an undisclosed location, under 24-hour police guard. Afterward it was revealed that they had her in a room at a
Holiday Inn.
End of siege On the evening of Tuesday, March 21, the adult hostages took matters into their own hands. They laced a glass of
iced tea with
Xanax, and after Palczynski drank it, he fell asleep. Andrew McCord fled out the front window, alone. Although he made a lot of noise in his panicked escape, Palczynski did not wake. Whitehead's mother also escaped. They left behind their son Bradley, who was sleeping on the kitchen floor, expecting police to rescue him. Fearing for the boy's life, officers broke into the home. There have been many discussions about why the parents left the boy behind. A documentary aired on British TV station
More 4 on April 7, 2010, said that they believed, because he was a child, if they woke him up he might be upset, make noise, and wake up Palczynski. They feared the man might kill them all then. They thought it best for the adults to escape and let the police rescue the boy. According to officers, Palczynski, who had last been seen lying on top of his weapons, had sat up and reached for a weapon. Officers shot him numerous times, killing him. While the events were shown live on television from a perimeter outside the house, viewers did not see the fatal shooting of Palczynski. ==Aftermath ==
