Deputies in Jefferson County are trying to identify two people who followed a worker home from the mall, robbed him at gunpoint inside his apartment and then left him hogtied.The robbery occurred at about 6 p.m. Monday at an apartment complex near West Coal Mine Avenue and South Arbutus Circle.The victim told police that he left Southwest Plaza Mall, where he works, and noticed a "brand new," black, four-door Cadillac in the parking lot as pulled out of the mall at about 5 p.m. During his drive home the victim said he noticed that the Cadillac appeared to be following him. When he turned into his apartment complex he saw the Cadillac turn in but then drive in the opposite direction.The victim then dismissed the idea that he was being followed and assumed the Cadillac's owner lived in the same complex.The victim then took his dog for a walk around the complex but when he returned home, he was approached by a man in a mask who pointed a handgun at him and ordered him inside.The victim was ordered to lie chest-down on the floor and face the wall while a second man began carrying out expensive items from the house. The men then duct taped the victim's hands and feet and hog tied his limbs together, the victim said.The men threatened the victim and ordered him not to call police. The victim lay still for several minutes to make certain the suspects were gone before finally freeing himself and calling the authorities."This was terrifying for this man, absolutely terrifying," said Jacki Kelly, spokeswoman for the Jefferson County Sheriff's Office. "And he's still very scared."About an hour later, a woman called Denver 911 to report something suspicious. It's a report that later helped police link surveillance videos to the home invasion robbery.She said she was sitting in the parking lot at the Wells Fargo Bank at Dartmouth Avenue and Sheridan Boulevard when she saw a man in a black Cadillac pull a ski mask over his face. He used the ATM machine at the bank, took the mask off and then drove away.The man then drove to King Soopers grocery store not far away and went inside, she said. A few moments later he exited the store and drove away.A Denver police officer arrived in the area and conducted a traffic stop on the Cadillac, which had three people inside.During the stop the driver left his vehicle twice and was ordered to return to his car. During his second return, the driver took off, and a short police pursuit ensued, the Jefferson County Sheriff's Office said. The home invasion robbery in Jefferson County had not yet been reported to the authorities so the officer ended the pursuit, per department policy.On Tuesday afternoon, police released surveillance pictures of the man who walked into the King Soopers store and the black Cadillac he was driving.The man is described as a white or Hispanic, in his mid 20s, about 5 feet 8 inches to 5 feet 10 inches tall. He is about 200 pounds, with a heavy build and brown hair. He was wearing a long-sleeved white shirt, blue jeans and white Puma tennis shoes with silver trim.The second man was wearing baggy blue jeans with yellow and red embroidered pockets, and white and black "skater" shoes, possibly Vans.The vehicle appears to be a black 2009 Cadillac CTS-V with chrome around the windows. The license plate on the suspect vehicle is # LNGLGS, which belongs to a stolen plate from Aurora.Anyone with information regarding this crime is urged to contact the Jefferson County Sheriff's Office tipline at 303-271-5612.
