Dallas police said that a man who has admitted to three sexual assaults in the Lake Highlands area was arrested Tuesday.
Three women were sexually assaulted by an intruder in their homes in less than one month.
Police Chief David Brown said Cesar Benitez, 33, has been charged in the Feb. 22 attack and the March 15 attack.
The latest news from around North Texas.
The department said Wednesday that Benitez would also be charged in the third attack, which took place on March 19.
The third attack, which occurred on March 19, remains under investigation while police determine the most applicable charges, Brown said.
Benitez admitted to all three offenses and voluntarily provided a DNA sample, Brown said.
The police chief said investigators received an anonymous Crime Stoppers tip on March 25 with specific information about a man the tipster believed resembled one of the police sketches that were released three days earlier.
"We believe he had been changing locations pretty regularly," Brown said. "We believe he was on the run. We have some information that led us believe he was heading back to Mexico."
Dallas officers saw Benitez at about 1 p.m. Tuesday on North Central Expressway and tried to conduct a traffic stop, Brown said. Benitez exited the freeway and abandoned his car in a parking lot. Officers pursued him on foot and arrested him.
"This was a needle in a haystack for us, and they put a lot of information together, a lot of different moving parts together in order to be at the right place at the right time, and the suspect came out," Brown said.
Benitez is charged with one count of aggravated sexual assault and one count of sexual assault. He is being held on a $4.56 million bond.
The department said Wednesday that it was also preparing to charge Benitez with burglary of a habitation with intent to commit sexual assault.
Police blanketed the Lake Highlands area with heavy presence after the attacks.
"The police presence has been very reassuring, and we were all very aware of it and very grateful for it," resident Nora Lundeen said.
But Lundeen said a man’s home in the neighborhood was also burglarized recently, but no arrest has been made.
“That is wonderful news -- it would be even better if I knew he’s the same guy that did the burglary," she said. "Then I’d feel a lot better."
