Assistant coroner Sarah Riley has issued a Prevention of Future Deaths report after the deaths of Eddie Hill, 20, and Jayden Long, 19, both from Norfolk. The two men died on Crib y Ddysgl in Eryri (Snowdonia) in February, a day after a 999 call from Mr Long was disconnected.
According to the report, Mr Long made the call to North Wales Police at 16:27 on 18 February. The connection was lost after he said "helo" and "allwch chi fy nghlywed?". The coroner found that very little further effort was made to identify who was using the phone, and more than three hours passed before mountain rescue teams were notified.
The mountain rescue team told the inquest that they did not have enough information about the location or nature of the call to respond immediately. After further inquiries, including contacting family members, teams searched around the last place the men were seen but found nothing. The search resumed the next morning, and bodies were found on 19 February.
In her report, Ms Riley raised concerns about a lack of guidance and training for staff handling emergency calls from remote mountain areas, as well as a lack of arrangements for sharing lessons learned. She said that if these concerns were not addressed, there was a real danger that more people could lose their lives.
North Wales Police said they had since revised their communications centre procedures. Changes include specific guidance for handling silent or disconnected 999 calls in remote or mountainous areas. The force said the concerns identified by the coroner had now been addressed.
