Montgomery County Police have a man in custody in connection with their investigation into the slaying of a Germantown woman and the disappearance of her 11-year-old son.

The son remains missing, according to Capt. Paul Starks, a police spokesman. Starks said locating the boy is the main focus of the investigation at present.

Police did not release the identity of the man in custody. They have not said whether he has been charged with a crime.

The missing car was found at 8:30 a.m. Thursday in the Charlotte, N.C., area, according to Starks. The man was taken into custody about an hour later.

A press conference to discuss the case and the search for the missing boy has been scheduled for Thursday afternoon.


The car belonging to a slain Germantown woman whose son is missing has been found unoccupied, Montgomery County police said Thursday.

Police believe the boy, 11-year-old William McQuain, was abducted and have issued an Amber Alert.

William was last seen two weeks ago, on Sept. 30, at the home he shared with his mother at Seneca Knolls Condos in the 1300 block of Briarcliff Terrace.

The boy’s mother, 51-year-old Jane McQuain, was found dead in her bedroom Wednesday evening around 8:25 p.m., hours after a friend reported she was missing, police said.

According to investigators, McQuain had suffered trauma to her body and her death has been deemed a homicide.

William McQuain, a sixth-grader at Martin Luther King Jr. Middle School in Germantown, is described as a black male with light skin, approximately 5 feet tall, and weighing about 85 pounds.

Police initially said they believed they would find him with the car, but the black Honda CRV was unoccupied. Police declined to say where the car was found, saying it could jeopardize the investigation.

Police do not have a suspect or motive in the boy’s disappearance or his mother’s slaying.

Maryland State Police ask that anyone with information about William’s whereabouts call 911 or 240-773-5070. Callers have the option to remain anonymous.
