O'FALLON, Mo. | A gunman shot and killed his ex-girlfriend and was fatally shot by police following a standoff Friday at an eastern Missouri medical center, authorities said.
The shootings took place at St. John's Mercy Urgent Care Center in O'Fallon, about 30 miles northwest of St. Louis. No patients or other clinic personnel were injured.
Capt. Dave Todd, who led the SWAT team that responded, identified the slain woman as medical center lab technician Jenenne Meadows, 47, of St. Peters. Authorities said the gunman was 45 years old, but his name was withheld while relatives were notified.
Todd called the deaths "a tragic ending to a tragic situation." He said the couple had lived together in St. Peters and had broken up one or two months ago.

The gunman entered the building about 4:40 p.m., brandished a gun and ordered people to leave, then went to the second floor and spent about 90 minutes with Meadows in a locked room.
Todd, the special enforcement commander for St. Charles County, said SWAT team members stationed in the hallway heard the pair arguing. They tried repeatedly to call the man on various phones, but he did not answer.
