All That Remains guitarist Oli Herbert died from drowning, his widow Beth revealed on Facebook. The 44-year-old guitarist went missing on October 16th and was found dead in a pond near his home in Connecticut. Beth wrote that an autopsy and toxicology report determined that her husband drowned after apparently ingesting antidepressant medication and sleeping pills. She explained, “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.'” Beth continued, “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.” She asked that anyone who knew where her late husband was getting the drugs he was taking should contact Troop C of the Connecticut state police. As for how Oli ended up in the pond, Beth later explained, “One of the drugs can have a hallucinogenic effect, also restlessness. Oli kept wanting to go outside that night before he disappeared and he kept walking towards the pond, which is a pitch black part of our property as well as very slippery. Add to that fact that it was raining that evening. Apparently he left the house after I went to bed so I couldn’t stop him and bring him back inside.” Beth also addressed the sudden cancellation of the public memorial service for Oli, which was supposed to be held on Sunday, November 11th in Worcester, Massachusetts. She wrote: “As far as why the memorial was cancelled; concern for my personal safety and home due to numerous threats to both is the reason.” Meanwhile, All That Remains has named guitar virtuoso and YouTube personality Jason Richardson as a temporary member of the band’s lineup for its December tour of Europe with Sevendust. All That Remains will be touring in support of its ninth LP, Victim Of The New Disease, which came out last week and features Herbert’s last recorded work with the band.
