Germantown Burglary Investigated; Suspect Shot by Resident

Detectives with the Montgomery County Police – Major Crimes Division are investigating the burglary of a Germantown residence that occurred early this morning.  During the burglary, the homeowner shot a 19-year-old male suspect who remains in serious condition with life-threatening injuries at a local hospital.

At approximately 2:11 a.m. on Saturday, April 1, officers from the 5th District responded to a burglary in progress at a home in the 11700 block of Tall Pines Drive in Germantown. Officers located a suspect in the backyard suffering from an apparent gunshot wound and they began life-saving measures while Fire and Rescue services was called.  Once emergency medical personnel arrived, the suspect was transported to a local hospital for treatment.

The preliminary investigation has revealed that the homeowner heard noises in the basement and believed his home was being burglarized. He armed himself with a handgun and went to investigate. He encountered two unknown suspects in the basement of his home. One of the suspects threatened to kill the homeowner. The homeowner discharged a firearm twice at that suspect, and apparently struck him with one of the rounds. The suspect is currently being treated at a local trauma center for life threatening injuries.

The description of the second suspect remains unconfirmed.

This remains an ongoing investigation.  Detectives are urging anyone with information about this event to contact the Major Crimes Division at 240.773.5070.


MCP Officer Struck By Vehicle On Interstate 270

Today, March 30, just after midnight,  Montgomery County Police – Sixth District officer Robert Sagona was traveling north on Interstate 270 (I-270) in the area of Montgomery Village Avenue (Maryland Route 124 – Exit 11) in his marked cruiser when he observed a black, Chevrolet Impala driving erratically in front of him at a high rate of speed.  A registration check of the vehicle’s tag indicated that the tag was not registered to that vehicle.  When Officer Sagona attempted to initiate a traffic stop on the vehicle, the driver failed to stop and continued to drive north on Interstate 270.  A pursuit of the vehicle was initiated.

Officers from the 5th District were alerted to the pursuit and deployed Stop Sticks on the northbound lanes of the roadway; the suspect vehicle’s tires were deflated and the vehicle was rendered inoperable.  The two occupants of the vehicle then fled from the vehicle on Interstate 270 just south of the exit for Clarksburg Road (Maryland Route 121 – Exit 16).

Officers from the Gaithersburg Police Department, the Maryland-National Capital Park Police Department-Montgomery County Division, and troopers from the Maryland State Police (MSP) assisted in the search for the suspects.  A MSP helicopter was also called to assist.  The suspects were not located.

During the search for the two suspects, Officer Sagona had walked from the northbound lanes of I-270 to the southbound lanes.  When the search was suspended at approximately 1:20 a.m., Officer Sagona began to return to his vehicle, which was parked on the northbound portion of I-270.  A Maryland State Trooper had positioned his marked vehicle to block the far right, southbound lane.  The driver of a 2011 Subaru Forrester, who was traveling south, moved from the right lane to avoid the MSP cruiser and struck Officer Sagona who was in the middle lane.

The driver of the Forrester is identified as Hunter Lee White, age 19, of Germantown.

Officer Sagona was airlifted to a hospital with serious, non-life-threatening injuries by the MSP helicopter that had come to assist in the search for the suspects.

The collision investigation is being conducted by the Collision Reconstruction Unit (CRU) and the  vehicle investigation is being conducted by the Central Auto Theft Section (CATS).

Officer Sagona, a Sixth District patrol officer, remains hospitalized in stable condition.  He has been on the Police Department for approximately four years.
