Weeks before Teri Lee and Timothy Hawkinson were killed in her second-floor bedroom, she spent $2,405 on an intrusion alarm system to protect herself against the murderer.
But when Steven Van Keuren, a jealous and disturbed former boyfriend who had already violated several orders for protection that prohibited him from contacting Lee, cut the phone lines outside her Washington County house in the early morning darkness of Sept. 22, 2006, nothing happened.
When Van Keuren shattered a glass patio door with a crowbar, a sensor stayed silent because it had been installed too far away, alleges attorney Bill Harper of Woodbury, who represents Lee's sister, Vicki Seliger Swenson.
The deaths, Harper contends, raise questions for thousands of Minnesota homeowners who rely on their intrusion alarms to protect them.
ADT officials declined to discuss the case, but in court filings they criticized local police forces for failing to arrest Van Keuren before the attack.
When Van Keuren crept up the stairs to Lee's bedroom, two new motion detectors didn't respond. The screeching alarm finally activated, Harper said, when Lee's two daughters opened the front door to escape -- after their mother was dead.
In a legal battle in U.S. District Court, Lee's family seeks punitive damages from ADT, contending that the company salesman misrepresented the alarm system's capabilities to Lee and that it was improperly installed, with deadly results.
"I think they are entirely misled as to what they're getting," Harper said.
