An ex-convict who killed seven people in July before taking his own life in a Grand Rapids shooting spree had pledged in a suicide note to take his mother-in-law "with me.'
Grand Rapids police released new information about the case Tuesday, including video and audio recordings.
Officials probably won't ever know with certainty why Rodrick Dantzler fatally shot a former girlfriend, his estranged wife, his 12-year-old daughter and four others related to them, including his mother-in law, Grand Rapids Police Chief Kevin Belk said.
