HI,
There is not a marked spot but go north-northwest on HWY 5 out of Van Alstyne about one mile There is a distinct drop in the road due to a creek passing under it. To your right will be a railroad. To your left is a modern log home nestled in some woods. This dip in the road is within a few yards where Captain Bill Wilson was gunned down by John Thompson and William Blackmore. If you can locate a grave, please let me know. I have tapped many local and regional resources, asking for help and received little in return. There just isn't enough historical evidence left.
