A police officer fatally shot a man at a southwest Houston business on Tuesday.
Houston police said the man went to the Terminix location in the 11700 block of South Sam Houston Parkway about noon.
The man's estranged wife works at the business. She had a protective order against the man, investigators said.
The estranged wife called police when the man showed up.
Detectives said an officer arrived as the man was walking to a cab, which he took to the location. Police said the officer told the man to not get inside.
"The suspect ignores and gets right back into the cab, proceeds to open and close the door repeatedly, as the officer is telling him, 'Get out of the cab. Get out of the cab. Let me see your hands,'" HPD spokesman Victor Senties said.
The man appeared to be searching for something under the seat, officials said.
"Suspect finally decides to exit the cab. Walking toward the business with one hand behind his back, (the) officer continues to have him at gunpoint, repeatedly telling him, 'Show me your hands,' which he does not do," Senties said.
Detectives said the man then started to bring his arm out from around his back. The officer fired one shot, killing the man, investigators said.
Police said the man was armed with a pistol. Detectives said they suspect that the man went to the business to kill his estranged wife.
Detectives said they believe the man went to the business about 2 a.m. and fired a shot into the office. The office was locked when the man arrived about noon because the estranged wife feared he would return.
The man's name has not been released.
