Detectives Investigate Domestic-Related Barricade in Colesville Area; Suspect Charged with First-Degree Assault

Detectives from the Montgomery County Police Department – 4th District Investigative Section have arrested and charged Jalen Christopher Marshall, age 25, of the 13500 block of Montvale Drive in Silver Spring, with the first-degree assault of his 72-year-old grandfather.  After assaulting his grandfather, Marshall barricaded himself inside the family’s residence and after approximately five hours of negotiations, Emergency Response Team (ERT) officers forced entry into the home and arrested him.

This morning at approximately 9:05, officers were called to a residence in the 13500 block of Montvale Drive for the report of domestic violence.  Upon responding to the home, officers were met with the 72-year-old victim, who had lacerations to his face.  Marshall, the victim’s grandson, was in the home.  When officers attempted to make contact with Marshall, he exited the home carrying what appeared to be a long rifle and then reentered the home.  (Officers located this weapon during a search of the home and determined that the long barrel replica firearm was a pellet gun.  See photo below).  Marshall exited and reentered the home several times carrying the rifle.  He told officers that he was going to drink bleach.  Emergency Response Team (ERT) officers were called to the scene to begin negotiations in an attempt to have Marshall exit the home peacefully.

While officers were trying to communicate with Marshall, the victim explained to investigators that Marshall, who lives with him and his wife (Marshall’s grandmother), had been acting strangely the past several days.  This morning, as the victim was in the kitchen and Marshall was upstairs, the victim heard a loud commotion coming from the upstairs.  Marshall came downstairs into the kitchen and began yelling at his grandfather.  Marshall punched his grandfather and pushed him to the ground.  While the victim was still on the ground, Marshall struck the victim’s face with a dining room chair.  The victim attempted to call 911 and run away but Marshall pushed him down again.  The victim was able to escape to the outside of the home as Marshall pursued him.  As the victim continued to attempt to get away, Marshall took a machete that he had in his vehicle and attempted to strike the victim.

The victim ran to a neighbor who was outside and the neighbor called 911.  Marshall ran back into the residence.

Shortly before 2:00 p.m., officers forced entry into the home and arrested Marshall. Marshall had used furniture to barricade himself inside of the home. During a search of the home, investigators located an approximately three-foot sword and the replica long gun that Marshall was carrying when he exited the home on several occasions (see photo below).

Marshall was transported to the Central Processing Unit and charged with first-degree and second-degree assault.  The grandfather was transported by Fire & Rescue personnel to a local hospital for medical treatment.

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.
