PALMER PARK, Md. (WUSA9) -- On the eve of the second anniversary of one of Prince George's County's most disturbing unsolved murder mysteries, investigators said Thursday that they are in their best position yet to crack the case.
"We believe we are in the best position we've been in in the two years of this investigation," said Capt. Jimmy Simms, the lead homicide investigator for the Prince George's County Police Department.
Seventeen-year-old Amber Stanley was shot to death in her bed by an intruder who kicked in the door of her family's Kettering home on August 22, 2012. Thursday, investigators said they do not believe the house was targeted at random but that Amber, an honor student at Flowers High School, may not have been who the intruder was actually after.
"We haven't received any information saying Amber Stanley was a specific target," said Maj. Cesar Pacheco, commander of the department's Criminal Investigation Division.
Two other people were in the house at the time of the late-night murder, including a foster child who was new to the home, police said.
The gunman fled from the house after the shooting without taking anything.
Detectives say they do not have a specific suspect, but that after interviews with nearly 100 people, the focus of the investigation has narrowed substantially and they are moving toward solving the mystery.
"We feel we're in a position now where we are heading in the right direction with where we want to go with the case," Capt. Simms said.
Detectives would not comment on potential theories or motives for what happened, saying their caution is a sign of how much closer they are to ending the intense investigation which they are taking pains not to spoil.
Investigators are still appealing for tips or information that might help.
