MEXICO CITY (AP) — Mexico City police said late Friday they are investigating a murder suspect as a possible serial killer after bones, a saw, blood and the ID cards of missing women were found at rooms he rented.

Mexico City prosecutors did not identify the suspect by name, but said that he was being held over for trial on charges of murder and attempted murder of two women.

Those charges stemmed from a brazen attack Tuesday in which the suspect apparently waited for a woman to briefly leave her apartment. He then rushed in and sexually abused and strangled her 17-year-old daughter.

The mother returned and saw him leaving, but he slashed her in the neck and fled. The mother survived but her daughter did not.

Because the suspect lived near the scene of the crime, he was quickly identified and caught. In keeping with Mexican law, police identified him only by his first name, Miguel.
