The men who gunned down Salvation Army Maj. Philip Wise didn't travel far to do it, investigators believe.

As his children looked on, Wise, 40, was gunned down on Christmas Eve as he returned to his North Little Rock, Ark., office to file paperwork. He had just dropped off two bell ringers on the final day of the Salvation Army's annual kettle drive.

Wise previously had served Salvation Army units in both Moundsville and Weirton. He and his wife, Cindy, who also is a Salvation Army major, had just adopted their children - ages 4, 6 and 8 - last year. The three are biological siblings who came from an abusive family.

Police believe two black men dressed in black clothing, both armed with handguns, approached Wise and his three children in the North Little Rock Salvation Army building's parking lot. One of the men reportedly demanded money from Wise before the fatal shot was fired.

North Little Rock police do not have any suspects in Wise's slaying, but they have received several phone calls with information on the case. On Tuesday, North Little Rock Police Department Sgt. Terry Kuykendall said investigators believe the men who killed Wise are from the Little Rock area.

"We don't see someone coming through here and committing that crime," he said. "We do believe they are local. ... There are a lot of different theories, but we just don't know. It's still too early to tell."

Authorities have raised $10,000 to offer for a reward for information that leads to the arrest and conviction of those responsible for the fatal shooting.

The North Little Rock Chamber of Commerce also is accepting donations to benefit the Wise family.

The children have been receiving counseling after witnessing their adoptive father's death.

Kuykendall said the children were standing beside their father when he was shot, but there apparently was no interaction between the youngsters and the two assailants.
