PASADENA, Texas -- The mother of two missing children said police are not doing enough to find them, KPRC Local 2 reported Monday.

"Do you know how it feels to not have your kids? You can't hold them anymore?" mother Jerilynn St. Cyr asked.

Pasadena police said 3-year-old Denim Sylvester and 7-year-old Randy Sylvester Jr. were last seen at an apartment complex at 4025 Burke Rd. at about 3:45 p.m. Sunday. Their family reported them missing at about 9:15 p.m.

St. Cyr said she is mad that Pasadena police are not doing more to help her family.

"Somebody came in my community and took my kids," said St. Cyr. "Pasadena is not trying to find them."

She said she has no idea where her two kids could be, but she does know one thing.

"We did not harm our children," she said. "We would never harm our children."

She said she and her husband are good parents to the children. She even showed Local 2 their room with their toys.

"Here's the PlayStation, the X-box, here are her stuffed animals," said St. Cyr as she pointed around the room.

Neighbors said the children loved to be outside.

"They're always out playing with other kids," said neighbor David Petty.

Neighbor Noel Shuler said she often worried about the kids.

"They're always wandering around the pools and the tennis courts," he said. "Anything could happen to them."

St. Cyr said she saw them last near a lamppost just outside the tennis courts, then they disappeared.

"We immediately started to search for our kids," said St. Cyr. "When night fell, that's when we alerted the police. When night fell."

Police said they had 20 officers out searching the area along with 25 volunteers, but stopped the active search at about 3:30 p.m. Monday because they exhausted all of their leads.

Meanwhile, people have been bringing toys and candles to a staircase at the apartment complex.

"I just went through my room and found that bear," said Joey Hosmer, a friend of Randy's.

Investigators said an Amber Alert was not issued for the children because the case did not meet the necessary criteria. Police said they did not believe there had been an abduction.

Police said the mother and father's stories were not consistent, but neither was ever considered a suspect.

St. Cyr said it is up to the community to find her kids.

"Mommy loves you and I will never stop looking for you," said St. Cyr.

Denim is 2 feet 5 inches tall, 35 pounds and was last seen wearing a pink V-neck T-shirt with brown trim, pink shorts and pink flip-flops. Her hair was braided with a pink ponytail.

Randy is 4 feet 1 inch tall, 55 pounds and was last seen wearing a blue and orange Florida Gators shirt, blue denim shorts and blue and white tennis shoes.

Anyone with information about the children's whereabouts is asked to call the Pasadena Police Department at 713-477-1221.
