On 08-20-2022 at approximately 7:30 pm, 17-year-old Demetrius Harbour was murdered in the east alley of the 2700 block of Gibson Street in Lake Station, IN. After a lengthy and thorough investigation, the case remained unsolved. In early 2025, detectives of the Lake Station Police Department took it upon themselves to form a Cold Case Unit, looking into all unsolved homicides in Lake Station dating as far back as 1975. Demetrius’ homicide became a priority case. After another year of investigating, and with the cooperation and direction from the Lake County Prosecutor’s Office, the following charges were filed this morning:
Keshaun Rey Perkins (already in custody on other charges):
COUNT I – MURDER (a Level 1 Felony)
COUNT II – MURDER (a Level 1 Felony)
COUNT III – ROBBERY RESULTING IN BODILY INJURY (a Level 3 Felony)
ENHANCEMENT TO COUNT I – FIREARM USED IN COMMISSION OF OFFENSE
ENHANCEMENT TO COUNT II – FIREARM USED IN COMMISSION OF OFFENSE
ENHANCEMENT TO COUNT III – FIREARM USED IN COMMISSION OF OFFENSE
Keontay Maurice Perkins (taken into custody in Lake Station, IN today):
COUNT I – MURDER (a Level 1 Felony)
COUNT II – ROBBERY RESULTING IN BODILY INJURY (a Level 3 Felony)
Mariana Jeanette Puentez (taken into custody in Gary, IN today):
COUNT I – ASSISTING A CRIMINAL (a Level 5 Felony)
COUNT II – ASSISTING A CRIMINAL (a Level 6 Felony)
COUNT III – OBSTRUCTION OF JUSTICE (a Level 6 Felony)
COUNT IV – FALSE INFORMING (a Class B Misdemeanor)
These resulting charges were truly a team effort from the Lake Station Police Department’s Cold Case Unit, with special thanks to Detective Cameron Price. His relentless pursuit of justice in this case, along with his excellent work ethic were paramount to this outcome. Also, a special thanks to the Lake County Prosecutor’s Office. This case would remain unsolved if not for their willingness and passion to assist by working closely with detectives during this investigation. We would also like to thank the following organizations that played a part in this outcome:
The Lake County High-Tech Crime Unit, and Coroner’s office; The Indiana State Police Lab and Crime Scene Investigators; The Lake Station Fire Department; St. Mary’s Medical Center; Hobart Police Department; The Northwest Indiana Major Crimes Unit.
