In a very comprehensive article by ABC news, they outline the alleged crimes Phillip Markoff, aka the Craigslist Killer, committed, and his likely motivation:
Philip Markoff, the accused “Craigslist Killer” currently being held in Boston on murder charges, gambled all night at the Foxwoods Casino two days after he allegedly killed Julissa Brisman. He also gambled at the Connecticut casino two days after he allegedly attacked another woman at the Westin Hotel in Boston, said the source, who spoke to ABC News on the condition of anonymity. Prosecutors claim he stole $800 out of the woman’s wallet before he bound her, duct-taped her mouth shut and then used plastic flexi-cuffs to tie her to a doorknob.
A police source close to the investigation told ABC News this week that police believe Markoff’s motive in the alleged crimes was to pay off gambling debts. Suffolk District Attorney Daniel Conley, speaking to reporters today after Markoff’s brief court hearing, would not comment on the gambling allegations, but said authorities believe robbery was the motive for the crimes.
The article goes on to describe just how terrible this crime was:
Prosecutors said today that Markoff bound and robbed a woman at the Westin Hotel on April 10. In a separate April 14 attack, prosecutors claim Markoff tried to rob 26-year-old Brisman at the Boston Mariott Copley Place Hotel, but hit her over the head and then shot her in the heart when she resisted.
“This is a brutal, vicious, savage attack. This suspect showed he was willing to take advantage of women,” said Conley, adding that there was a “strong possibility he has done this before.” During a search of Markoff’s house, police found a semi-automatic weapon, plastic ties and duct tape, Conley said.
