Detectives from the Montgomery County Police 5th District Investigative Section are seeking help from the public as they investigate a robbery and assault that occurred on Monday, September 17 at approximately 8:35 p.m. on Laytonsville Road in Laytonsville.

Today they are releasing a computer-generated composite sketch of the suspect.

The investigation revealed that the adult female victim was driving a black 2017 Toyota Rav4 Sports Utility, when she pulled over in the 23600 block of Laytonville Road to use her phone. She did not notice that a car pulled up and stopped behind her.

While she was on the phone, the unknown male suspect got out of his car and walked up to her car. She did not open her door, but rolled down a window. The suspect demanded cash and she complied. He then reached in through the open window to assault her.

As the suspect saw other vehicles approaching, he ran away and got back into what is described as a small, black, four-door vehicle, possibly a Mazda. He drove off on Laytonsville Road towards Laytonsville.

The suspect is described as a black male, of unknown age, 6’ 2” tall, weighing 175 pounds, with brown eyes, very short black hair and has a gold upper tooth. He was wearing black jeans and a long-sleeved black T-shirt.

Detectives are asking anyone who can identify the suspect, or who was driving in the vicinity during the time of this incident and may have seen the encounter, to call them at 240-773-6237.

Update: Officer-Involved Shooting at Domestic-Related Barricade

Update: July 26, 2018: John Carlos Natera-Perez succumbed to his injuries yesterday evening.  His body has been transported to the Office of the Chief Medical Examiner (OCME) in Baltimore for an autopsy.


Detectives from the Major Crimes Division continue to investigate a domestic-related barricade situation and officer-involved shooting of the suspect that occurred at a townhouse in the Fairland area last night.

The officer involved in the shooting is identified as Officer Edward Cochran, an eight-year veteran of the police department who is currently assigned to the Tactical Unit (SWAT Team).  He is on administrative leave per department protocol.

John Carlos Natera-Perez, also known as Jean Perez, who is 30 years old, of an unconfirmed address, is in grave condition and is not expected to survive.

On Monday, July 23, at approximately 7:57 p.m., 3rd District officers responded to the report of an assault at a townhouse in the 2800 block of Mozart Drive in the Fairland area. The first call to 911 was reported to be a woman screaming. The call taker heard a male voice state, “I will kill you,” and the line was then disconnected.

As the first officer arrived, he observed Mr. Perez standing in the townhome doorway, with blood on his clothing and holding a knife.  The officer called for Mr. Perez to exit the home.  Mr. Perez stepped back into the residence and shut the front door. A female, later identified as a resident of the home and Mr. Perez’ ex-girlfriend, was standing outside in front the house.  She immediately advised the officer that her three-year-old son was upstairs in his bedroom.  The female further stated that Mr. Perez had entered the residence, confronted the woman and her boyfriend, and assaulted them before the two were able to flee from the home.  Officers also learned from the female that Mr. Perez was the father of the child in the residence.

Officers attempted to make contact with Mr. Perez, but these efforts were unsuccessful. The Emergency Response Team (ERT) was called to the scene at approximately 8:08 p.m.  Once ERT members arrived, negotiators contacted Mr. Perez via a loud speaker in English and in Spanish, instructing him to exit the home and/or release the 3-year-old child. Although Mr. Perez made some verbal responses, he refused to exit the home and refused to release the child.  These negotiations continued for more than an hour.

During this time, officers observed Mr. Perez using furniture to barricade doors and windows inside the home. Officers also saw Mr. Perez writing on the windows using what appeared to be blood on his fingers.

At approximately 10:15 p.m., officers observed Mr. Perez light something on fire and throw it out a second-floor bedroom window onto the ground below.  Several minutes later, the child was heard screaming.  Mr. Perez then began to light clothing in the home on fire.  Smoke was observed coming from the bedroom and the townhome’s smoke alarms began to sound.  Tactical team supervisors made the decision to enter the home due to concern for the child’s welfare. During this tactical operation, Perez was shot while he was in the master bedroom.  Officers were then able to get to the second floor of the house where they located the child unharmed on the bed in the master bedroom.  Officers found a knife with blood on it on the bed.  The child was taken from the home by tactical officers.  Officers and Fire & Rescue personnel administered life-saving efforts on Mr. Perez and he was transported to a local hospital in grave condition.

A search of the home revealed charred clothing in two areas of the second floor. A flammable liquid and three lighters were located in the master bedroom.

Further investigation by detectives, to include a review of court documents, has revealed a history of prior domestic violence between the suspect and female victim.  According to the victim, this violence occurred as recently as three weeks ago when she and the son were both assaulted by Mr. Perez.

This investigation is ongoing. As more information is able to be confirmed, it will be released.

Update: Robbery and Assault Immediately Preceded Hewitt Avenue Fatal Hit and Run; Suspects Arrested

Kenneth Sahr Kpakima

Detectives from the Montgomery County Police Department – Major Crimes Division and from the Collision Reconstruction Unit (CRU) have been investigating the Friday, June 8 assault, robbery, and death of 40-year-old Gregory Jonathan Atwood, of Tynewick Drive in the Bel Pre area.

On Tuesday, June 19, detectives arrested Mohammed Salous, age 17, and charged him as an adult with assault-related offenses for his involvement in the robbery of Gregory Atwood.  On Wednesday, June 20, Kenneth Sahr Kpakima (also spelled Kapakima), age 21, was charged with assault and armed robbery offenses related to this crime.  They are both being held without bond.  A 15-year-old female suspect has been identified but has not been charged at this time.

Investigation by detectives revealed that on Friday, June 8, at approximately 3:50 a.m., 4th District officers responded to southbound Georgia Avenue at Hewitt Avenue for a person in the roadway.  Responding officers located Gregory Atwood, deceased in the southbound lanes of Georgia Avenue.  There was evidence of trauma to his body.

Preliminary investigation at the scene by CRU detectives indicated that Atwood was struck by two separate vehicles.  The drivers of those vehicles did not remain on the scene.  Evidence further indicated that one of the involved vehicles is possibly a 2011 Chrysler 200 or a 2011 Dodge Avenger (unknown color).  CRU investigators believe that the second vehicle involved in this collision is a light-colored Dodge Durango.

During the joint investigation by CRU and Major Crimes detectives, a review of surveillance video in the area of Georgia Avenue and Hewitt Avenue showed that prior to the collision being reported on June 8, Kpakima, Salous, and the 15-year-old female assaulted and robbed Atwood of his property in that area.  Detectives have further determined that Atwood suffered injuries as a result of that assault and that the suspects fled from the scene after they assaulted Atwood.

CRU detectives continue to investigate the hit and run portion of this investigation.   There is considerable vehicle and foot traffic in the area of Georgia Avenue at Hewitt Avenue, even at the time when this robbery and subsequent hit and run collision occurred.  CRU Investigators are urging anyone who may have witnessed this collision, who were in the area around the time of this collision, saw something suspicious, or may have any information about this collision, to please call the 4th District Police Station at 240-773-6620.  Callers may remain anonymous.
