HOUSTON -- Houston Police are mourning the loss of one of their own, who was fatally shot during a traffic stop on Sunday morning. Dozens of officers joined the victim's family at Memorial Hermann Hospital where the 11-year-veteran was pronounced dead. The officer was shot at 8:40 a.m., shortly after he pulled over a Dodge Durango at the Luxor Apartment Complex at 5801 Sunforest Drive. Police say the driver jumped out of the SUV and ran into the complex with the officer following close behind. Witnesses told police the suspect then turned around and shot the officer several times. He was rushed to the hospital by ambulance in critical condition, and an unconfirmed report suggests the officer may have been shot in the head at least once. Police are not sure if more than one person was involved in the incident or if the officer was able to return fire. Less than an hour after the shooting, Harris County Sheriff's Deputies apprehended a person of interest near West Green's Road and Veterans Memorial, but they stopped short of calling him a suspect. HPD says they have stepped up patrols in the area where the shooting occurred due to a high concentration of drug and gang activity. The officer's identity has not been released. Houston Police Chief Harold Hurtt says the victim's wife and adult daughter have been notified, but they have yet to reach a son who is in the service and stationed in Italy. Mayor Bill White also released a statement to the media, asking the community to support the officer's family and fellow officers. "I encourage all Houstonians to keep the officer's family in their prayers. We are lucky to have people who risk their lives for our safety," said Houston Mayor Bill White. Houston police have a suspect in custody accused of fatally shooting an officer during a traffic stop on Sunday. The suspect, who police are expected to name later Monday morning, is charged with capital murder of a police officer and is scheduled to appear in court Tuesday. Police say the suspect shot Officer Tim Abernathy on Sunday at approximately 8:40 a.m. shortly after Abernathy stopped the suspect's Dodge Durango at the Luxor Apartment Complex at the 5800 block of Sunforest Drive. The man accused of killing Houston police Officer Timothy Abernethy has an extensive Harris County criminal history dating back at least to 1998, with convictions for offenses ranging from drunken driving to narcotics trafficking. Mabry Landor, also known as Marby Landor, was charged early today with capital murder in the slaying of Abernethy, an 11-year Houston Police Department veteran who was gunned down after a traffic stop. Landor, 28, pleaded guilty in November 2007 to driving while intoxicated after his arrest in July by a Harris County sheriff's deputy. It was his third DWI offense. Landor received a two-year prison sentence, according to Harris County criminal records, but it was not immediately clear this morning how much of that sentence he actually served. He was charged in January 2006 with possession with intent to deliver a controlled substance, pleading guilty later that year and receiving a two-year prison sentence. In April 2003, Landor was sentenced to 30 days in the Harris County Jail after he was convicted of delivering marijuana. In March 2005, he was charged with burglary after breaking into a home in Harris County. The charge was reduced to assault in December that year and Landor pleaded guilty and was sentenced to 333 days in the County Jail. Landor was convicted of assaulting a family member in August 2003, receiving a 35-day jail sentence after his guilty plea. In August 2002, he pleaded guilty in a Harris County hit-and-run case and was sentenced to 10 months behind bars. UPDATE: Officer Abernethy was working overtime yesterday in a part of northwest Houston so dangerous police include it in a "hot spot" program to put more officers on the street. Police say Abernethy pulled over a vehicle for a minor traffic violation and had submitted the car's license plate to a dispatcher -- when the driver ran. Abernethy, who was working alone, chased the man through an apartment complex. Witnesses say the man ducked behind a wooden gate and when Abernethy ran by -- the officer was shot in the head. Abernethy is survived by a wife and two children.
