The NYPD is investigating whether the brutal stabbing of a 17-year-old girl in Queens is connected to a similar incident in the borough in June. Around 11:30 on Monday night Natasha Martinez was walking home from her job at McDonald's when she was stabbed in the back and torso 11 times near her Woodhaven home on 85th Street. She says her assailant attacked her without provocation and ran off when her mother burst out of the house to help.

“I heard her calling me from downstairs outside and I thought that she just forgot her keys to get inside," Martinez's mother told the Post. "Then I heard her screaming, ‘Mommy, Mommy, help me, help me!’ I ran downstairs and my daughter was stabbed full of holes. Blood was pouring out of her body. And she fell down and I held her in my arms. She said, ‘Mommy, I feel like I’m going to die.’ "

Martinez is listed in stable condition at Jamaica Hospital, where doctors removed her spleen. A man wearing a hooded sweatshirt was caught on security camera strolling away from the scene, looking back over his shoulder.

NYPD Commissioner Ray Kelly told NBC New York that investigators are working to determine if the stabbing is connected to another mysterious attack on a woman in front of her house in June. That attack happened in Queens Village in the early morning of June 25th. Like Martinez, victim Kerline Denizard was also near her home when she was stabbed in the throat, arms, and back.

Family members told the Daily News that Denizard was leaving for her job as a home health care aide (she works with disabled children) at 4:45 a.m. when she was attacked on 221st Street steps from her car. A man whom police describe as a 6-foot, 5-inch black man wearing a black hoodie stabbed her repeatedly and then ran off, taking nothing. Denizard sustained critical injuries, but lived. No arrests were made. Both investigations are ongoing.
