Someone wanted Brandon Lincoln Woodard dead — bad enough to apparently lure him to a midtown Manhattan block for what looked like a professional hit.

But who shot Woodard in the back of the head and why remained a mystery on Tuesday as police studied security videotape of the unidentified gunman and delved into Woodard's checkered past for clues.

The brazen slaying of the 31-year-old visitor from Los Angeles"certainly appears to have been planned," Police Commissioner Raymond Kelly told reporters.

Based on the videotape, New York Police Department detectives suspect Woodard was lured into the Monday afternoon ambush shortly after he checked out of a hotel on nearby Columbus Circle, Kelly said.

The killer had arrived at least 30 minutes before the gunfire erupted in a normally safe neighborhood teeming with car and pedestrian traffic. The man, who appears to be bald and have a beard, could be seen exiting the passenger side of a parked Lincoln sedan and pacing as he waited, police said.

After Woodard got there, he checked his phone and walked back and forth as if looking for an address, police said. When the shooter approached, Woodard appeared to look back at him for a split second. He looked away again after "showing no sign of recognition," Kelly said.

A security photo — released to seek the public's help in identifying the gunman — shows him reaching into his pocket for a pistol moments before he fired a single deadly round.

Afterward, the shooter left Woodard in a pool of blood on the sidewalk, slipped into the same Lincoln sedan and was driven away. A vehicle fitting the description of the sedan was last seen going through the Midtown Tunnel.

Ballistics evidence pointed to a possible lead: The 9mm semiautomatic used to kill Woodard was the same weapon used to last month to shoot up the outside of a home in Queens where nobody was hurt. Police also recovered two phones carried by the victim.

Investigators were still trying to determine what Woodard — who checked into his hotel on Sunday after flying in from California on a one-way ticket — was doing in the city. Kelly said he has been described as a promoter but had no further details.

Kelly declined to comment on news reports that Woodard's mother ran a mortgage business in California that was mired in litigation and other troubles.

Sandra and Rodney Wellington, the mother and step-father of Woodard, released a statement Tuesday urging anyone with information on the killing to contact New York City police detectives.

"There are no words to express our shock and sadness in the face of our family's horrendous tragedy. We eagerly await justice for Brandon," the statement said.

They described him as a "gentle and generous young man," a devoted father and loving son who loved sports.

Woodard graduated from Campbell Hall High School and earned a Bachelor's degree from Loyola Marymount University, the statement said.
