Pregnant woman, boyfriend killed in botched home invasion on Staten Island

A pregnant woman and her boyfriend were fatally shot inside their Staten Island home Monday by a convicted killer during a botched home robbery, ­sources said.

A suspect, Philip Moreno, 45, allegedly stormed into the home in Arlington at about 5 p.m. and gunned down both victims in the living room, according to law enforcement sources.

Ana Desousa, 33, who was pregnant, and her partner, Alafia Rodriguez, 46, were discovered dead on the floor by police.

Cops quickly found Moreno nearby, allegedly carrying a gun and zip ties he apparently intended to use on the couple, the sources said.

A third victim, an unidentified 43-year-old woman, was also found in the living room with a gunshot wound to the back, cops said.

She was taken to Richmond University Medical Center, where she was in critical condition Monday night.

Authorities found an unharmed 2-year-old girl, believed to be the slain couple’s daughter, inside the home. The toddler was taken to the same hospital to be evaluated.

Moreno, who allegedly was carrying a .22-caliber Ruger when cops caught him, was arrested in July 1992 for the murder of ­Theodis Watson on Staten Island, sources said.

A year later, he copped to manslaughter and was jailed upstate in Sing Sing, according to the Staten Island Advance.

He was paroled in 2007, sources told The Post.

At a Monday night press briefing, NYPD Assistant Chief Kenneth Corey said Moreno has several other gun-related convictions.

Charges against him were pending early Tuesday.

Corey told reporters that drugs were found at the scene. “I can tell you that I observed narcotics and narcotics paraphernalia,” he said.

A police source said the drugs were cocaine.

Corey also said a silencer was recovered at the scene.

Monday’s double homicide raises the total number of murders this year in the 121st Precinct to three.
