LITTLE ELM (CBSDFW.COM) – Little Elm Police Chief Rodney Harrison went into detail about the events of Tuesday afternoon when Detective Jerry Walker was shot to death by a man inside a house.

That man was later found dead. Police have not yet released his identity while investigators await confirmation from the Medical Examiner’s office.

Chief  Harrison said after Walker and others arrived to investigate a man yelling in his backyard while carrying a rifle, the man went inside and started firing through a door or window.

“The suspect never stepped outside the home.  His attack on officers was from a hidden position,” said Chief Harrison.

Police said Detective Walker lived only two blocks from where he was killed.

Chief  Harrison said the SWAT team was arriving and getting in place as the shooting happened.  Paramedics came up in an SUV and moved Walker away from the area before he was rushed by CarFlite to Denton Medical Center where he later died.

Chief Harrison said about two hours into the standoff, police became aware an elderly woman, believed to be the grandmother of the suspect, was inside the home with him.  She was able to escape through the back of the house.

Police sent in a robot to look for the suspect and discovered the suspect was dead.

It is not yet clear if the suspect took his own life or if he died from returned fire from police.  The Texas Rangers are investigating the case.

“Its been very, very tough,” said Chief Harrison. “We have a young police department, a growing police department. A lot of our officers have never been exposed.  In fact there’s very few officers that have been exposed to something like this.”

Neighbors told CBS11, the suspect is no stranger to police.  People who live near the home said police have responded to disturbance calls there before.

“For years now, the person we rent from said there’s been ongoing problems. The family knew not to let him have weapons. They don’t know where he got the rifle from,” said next door neighbor Matthew Tempest.

“He likes to walk, roam freely, didn’t cause trouble, but he’s known to in the past, the police have been called to the house a couple of times,” said another neighbor Juan Martinez.

Also, Congressman Michael C. Burgess, M.D. (R-TX), issued a statement on the passing of Detective Walker:

“It is the selfless dedication and courage that our law enforcement officers exhibit every day that keep us safe. This morning the town of Little Elm mourns the loss of one of our heroes in blue, Detective Jerry Walker. I had the privilege of meeting Detective Walker while he was on duty at one of my town halls in the summer of 2014. The simple presence of the police force in a community provides a sense of safety and security for its citizens. While every instance of violence that results in the death of a police officer is devastating, this loss has cast a shadow of sadness over our community. I extend my deepest sympathy to Detective Walker’s family and continue to keep them in my prayers.”
