Police found the remains of a missing 24-year-old pregnant Philadelphia woman and arrested her former boyfriend, authorities announced Saturday.

The suspect, Stephen Poaches, is a former boyfriend of 24-year-old LaToyia Figueroa, who has been missing for a month. When Poaches, 25, was arrested in nearby Chester, police said he was wearing a bulletproof vest and carrying a pistol.

District Attorney Lynne M. Abraham said Poaches, 25, would be charged with two counts of murder and related offenses for the deaths of Figueroa and her fetus.

Authorities did not provide a motive or say what led them to suspect Poaches. Poaches' lawyer, Michael Coard, did not immediately return a phone call seeking comment.

Figueroa, who was five months' pregnant when she disappeared and the mother of a young girl, was last seen on the afternoon of July 18 in West Philadelphia.

Philadelphia police recovered her remains early Saturday in nearby Chester, located about 13 miles southwest of Philadelphia.

LaToyia Figueroa's father, Nelson Figueroa, said he was relieved that an arrest had been made.

"Now she can rest in peace," he said. "All I want is justice with that peace."

The remains were recovered in a grassy, partially wooded lot near homes and a road in Chester. The area was cordoned off by yellow police tape Saturday morning.

A few dozen members of the Figueroa family and supporters arrived at the scene shortly after daybreak, clustering close to the police tape and embracing each other.

"Our hearts our broken ... we just want to spend some time here and take a look at this place where LaToyia unfairly was murdered," said Philadelphia City Councilman Juan Ramos, a cousin of Figueroa.

Relatives and friends, who have papered the city with flyers and held large-scale searches for any sign of Figueroa, had just marked the one-month anniversary of her disappearance. A reward fund for information had reached $100,000.
