COLORADO SPRINGS, Colo. (AP) — Robert Lewis Dear was reclusive, and he seldom spoke to neighbors in a quiet patch of woods in rural Colorado where he lived.Now, it's his words that are drawing the most attention as police try to discern his motivations for a shooting attack they say he carried out Friday at a Planned Parenthood clinic in Colorado Springs that killed three people, including a police officer.After his arrest, Dear said "no more baby parts," said a law enforcement official, who could not elaborate and spoke on condition of anonymity because the official was not authorized to speak publicly about the ongoing investigation.Planned Parenthood cited witnesses as saying the gunman was motivated by his opposition to abortion.The attack thrust the clinic to the center of the ongoing debate over Planned Parenthood, which was re-ignited in July when anti-abortion activists released undercover video they said showed the group's personnel negotiating the sale of fetal organs.Planned Parenthood has denied seeking any payments beyond legally permitted reimbursement costs for donating the organs to researchers.
