The gunman who killed two teenage sisters Sunday inside a Colorado Springs church has been identified as Matthew Murray, ABC News has confirmed.
Authorities have not said whether Murray, a 24-year-old from Englewood, Colo., who was killed by a security guard at the New Life Church after he fatally shot two teenage sisters, was also responsible for the shooting rampage at a youth missionary in the Denver suburb of Arvada, about 70 miles from Colorado Springs.
Earlier today, Colorado Springs police announced that Stephanie Works, 18, and Rachael Works, 16, were killed Sunday morning after services at New Life Church. Their father, David Works, 51, suffered two gunshot wounds to the stomach and groin and is listed in fair condition.
Judy Purcell, 40, was shot in the right shoulder, and Larry Bourbannais, 59, was shot in the left forearm. Both were treated and released from an area hospital.
Rev. Brady Boyd of the New Life Church said in a news conference this morning that the gunman was not a member of the church.
"It was just absolutely random. It was a tragedy. He simply showed up on our property yesterday with a gun intent to harm people and that's what he did," Boyd said.
Twelve hours earlier, two people were killed at Youth With a Mission missionary center in the Denver suburb of Arvada, which is about 70 miles from Colorado Springs.
New Life Church leaders beefed up security after hearing about the shootings in Arvada. Boyd called the plainclothes security guard a "hero."
"There could have been a great loss of life yesterday," Boyd said. "She probably saved over 100 lives. She rushed toward the attacker and took him down in the hallway."
Police searched a home in Englewood, Colo., early this morning, trying to determine whether the two separate shootings in Colorado churches this weekend are related.
Police said they believed the shootings were probably linked, though there is currently no evidence to prove that.
"Given the circumstances, I think it is a good possibility that the two are linked," Arvada Deputy Police Chief Gary Creagor told The Associated Press early today, "but we have to prove that they are."
At the Youth With a Mission center, terror struck just after midnight Sunday. The young missionary students were wrapping up a Christmas party when a man came to a side door, asking to stay the night.
After his request was denied, the young man opened fire with a handgun, killing 25-year-old Tiffany Johnson, from Duluth, Minn., who answered the door, said the Rev. Peter Warren, the director of Youth With a Mission.
"She was just a wonderful young lady," Warren said of Johnson. "She had big dimples. Everyone loved her."
Phil Crouse, a 22-year-old from Alaska, was also killed. Warren said Crouse was "quiet but pleasant" and a "really hard worker."
Dan Griebenow, 24, and Charles Blanch, 22, staff members at the center, were wounded.
"All of these guys are so tight, so close," Warren said. "It just makes it all the more painful."
Police arrived minutes later, but it was too late. The gunman, reportedly a white man in his 20s dressed in black, was already gone.
