Earlier this week, two brothers appeared in court charged with murdering Blake.
Stephen McGlinchey, 27, from Ballyhanedin Road in Claudy and Andrew McGlinchey, 29, also from Roe Mill Gardens in Limavady, were jointly charged with the teenager’s murder.
Blake was found by police at a house in Limavady’s Woodland Walk on Friday, February 2.

Both were remanded in custody to Maghaberry prison.
Meanwhile, detectives from the PSNI’s Major Investigation Team are today, Friday, February 9, making a specific appeal, one week on from the murder of Blake Newland.
The teenager was stabbed multiple times in the Woodland Walk area of Limavady on Friday night, 2 February. Sadly, he later died from his injuries.
Detective Chief Inspector Mark Gibson said: “Blake was just 17 years old when his life was taken.
“This was the most tragic loss of a young man’s life. A loss which has left a community in shock and loved ones bereft.
“It is now one week on. And I’m keen to, first of all, extend sincere thanks to those who have assisted our investigation to-date.”
Detective Chief Inspector Gibson added: “I’m also making a specific appeal for footage, whether CCTV, mobile phone, or dash cam.
“Were you in the Woodland Walk area of Limavady on Friday 2 February, between 8.30pm and 9.50pm?
