Beth Hill was shopping at Macy's in downtown St. Paul in January 2010 when she got the phone call she'd been waiting years to receive.
"Tom, do you have something good to share with me?" she asked St. Paul police Sgt. Tom Bergren in what had become her automatic response to his many calls.
Bergren and a team of investigators from several law enforcement agencies had been doggedly investigating a 2007 triple shooting that killed Hill's son, his girlfriend and the woman's 15-year-old daughter. Each was killed by a gunshot to the head.
That day over Hill's lunch break, Bergren finally could say yes, he had something good to share: A federal grand jury had indicted two men on three counts of murder in the deaths of her son, Otahl Saunders, 31; Maria McLay, 32; and McLay's daughter, Brittany Kekedakis.
"I remember my ears were ringing," Hill recalled Thursday at an awards ceremony for the team that solved the murders. "My heart was pounding."
Bergren and several others were recognized by Police Chief Thomas Smith for their work on the difficult case. The suspects, who have violent histories, left behind little physical evidence and intimidated witnesses.
"This was a crime of unthinkable horror," Smith said. "[Bergren] never gave up. He was the glue that held this investigation together."
Bergren received the Medal of Commendation, as did officer Rob Merrill, Sgt. Jane Mead, Sgt. Shay Shackle and retired Sgts. Tom Dunaski and Jane Laurence.
