All That Remains guitarist Oli Herbert's widow, Beth, has released a statement via Oli's Facebook page revealing his cause of death, which was drowning. She explains that he had "apparently" been self-treating manic-depression by taking anti-depressants, which were found in his system along with a sleeping aid.

She adds that his public memorial was suddenly cancelled due to concerns for her personal safety, as "numerous threats" have been made against her. You can read her statement in full below.

Good morning everyone this is Beth. And indeed it IS a good morning; Toxicology results are back as is the official cause of my husband's death!

Cause of death- Drowning
Toxicology- Oli was apparently self-treating for manic-depression that has run in his family for several generations. Anti-depressants were found in his system, as well as a sleep aid. The psych meds found in his system were the same ones that a close relative has been prescribed for a long time, so he knew what to hunt down for the "treatment". Seeing how he was not going (and WOULDN'T GO) to a doctor to get diagnosed with the issue and was not being prescribed the medications and monitored on them, it explains his occasional erratic behavior here at home.

As far as why the memorial was cancelled; concern for my personal safety and home due to numerous threats to both is the reason.

If anybody knows where Oli was getting the psych meds, please call CT State Police, Troop C in Tolland, CT.

Herbert died on Oct. 16 at the age of 44. Before he passed he had completed work on All That Remains' latest album, Victim of the New Disease. The record was released yesterday (Nov. 9).

Frontman Phil Labonte revealed exclusively to Loudwire that former Chelsea Grin and Born of Osiris guitarist Jason Richardson will serve as Herbert's fill-in for the band's upcoming tour.
