HENDERSON (KTNV) — UPDATE MAY 20: New details are emerging about the Henderson man accused of killing his wife.

Authorities say Alan Sylwester's previous wife died under suspicious circumstances in California and police in Henderson said they started questioning him in March after noticing strange marks on his second wife's, later identified as Karen Byrer, wrist after he claimed to find her deceased in bed.

Sylwester has been charged with the murder of Byrer, but not charged in the death of his first.

Livermore police said he was questioned about that incident and not ruled out as a suspect as the investigation there remains open.

An autopsy in Clark County determined Byer died of asphyxiation with the coroner ruling her death a homicide.

Detectives also learned Sylwester's first wife died under suspicious circumstances in 2011.

Police in Northern California said Laura Gilliom died from an overdose of prescription medications, but detectives are discussing the two cases – noting similar circumstances - including bruising on both wrists and claims of "rough sex" by Sylwester before the women passed.
