It was a grant of a lifetime…and then it wasn’t. Yesterday, WHAV reported Ruth’s House, a popular Lafayette Square thrift shop with a charitable mission, was to receive a nearly $100,000 state grant to bolster security. The information came Wednesday in a press release from the state Office of Grants and Research. The release clearly listed “Ruth’s House, Haverhill, $98,797.02” under Commonwealth Nonprofit Security Grant Program. Unfortunately, the state admitted Thursday, that despite listing “Haverhill” specifically, the grant was actually awarded to JGS Housing Services, doing business as Ruth’s House of Longmeadow, a nonprofit assisted living facility.
